## Pattern Assignments
### `apps/pwa/src/App.tsx` — add `paddingBottom` to phone `contentStyle`
**Analog:** self, lines 154163
**Current contentStyle (lines 155163) — the gap to fill:**
```ts
// App.tsx lines 155163
const contentStyle: React.CSSProperties = {
flex: 1,
minWidth: 0,
minHeight: 0,
display: 'flex',
flexDirection: 'column',
overflow: 'hidden',
position: 'relative',
// ← paddingBottom is ABSENT — this is the defect site
};
```
**Phone branch pattern (isPhone() defined at line 64):**
```ts
// App.tsx lines 64, 84 — the phone boolean already exists
function isPhone(): boolean {
return typeof window !== 'undefined' && window.matchMedia('(max-width: 767px)').matches;
}
// ...
const phone = isPhone(); // line 84
```
**After fix — spread operator pattern (matches existing outerStyle pattern at lines 144-152):**
```ts
const contentStyle: React.CSSProperties = {
flex: 1,
minWidth: 0,
minHeight: 0,
display: 'flex',
flexDirection: 'column',
overflow: 'hidden',
position: 'relative',
// Phone-only: reserve space for the fixed BottomTabBar
...(phone ? { paddingBottom: 'var(--bottom-chrome-h)' } : {}),
};
```
---
### `apps/pwa/src/components/CalendarShell.tsx` — fix FAB `bottom` offset
**Analog:** self, lines 463491 (the FAB block)
**Current FAB style (lines 468487) — the defect site:**
```ts
// CalendarShell.tsx lines 463-491
{phone && (
<button
aria-label="New Event"
onClick={() => setEventForm(true, 'create')}
style={{
position: 'fixed',
bottom: 'var(--space-6)', // ← DEFECT: 24px — behind the 56px BottomTabBar
right: 'var(--space-6)',
width: '56px',
height: '56px',
minWidth: '56px',
minHeight: '56px',
borderRadius: '50%',
background: 'var(--color-text-primary)',
color: '#ffffff',
border: 'none',
cursor: 'pointer',
display: 'flex',
alignItems: 'center',
justifyContent: 'center',
boxShadow: '0 4px 16px rgba(0,0,0,0.18)',
zIndex: 100,
fontFamily: 'var(--font-family-base)',
}}
>
<Plus size={24} aria-hidden="true" />
</button>
)}
```
**After fix — change only the `bottom` line:**
```ts
bottom: 'calc(var(--bottom-chrome-h) + var(--space-6))',
// FAB sits var(--space-6) (24px) above the BottomTabBar top edge
```
---
### `apps/pwa/src/components/BottomTabBar.tsx` — optional token reference
**Analog:** self, line 73
**Current inline height (line 73) — unchanged but optionally can reference token:**
```ts
// BottomTabBar.tsx line 73
height: 'calc(56px + env(safe-area-inset-bottom, 0px))',
// This resolves identically to var(--bottom-chrome-h) — token reference is optional
```
**isPhone() pattern (lines 2325) — same function, confirmed project-wide:**
```ts
function isPhone(): boolean {
return typeof window !== 'undefined' && window.matchMedia('(max-width: 767px)').matches;
}
```
**Tab active/inactive style pattern (lines 2750) — for admin two-tab analog:**
```ts
const tabBase: React.CSSProperties = {
flex: 1,
display: 'flex',
flexDirection: 'column',
alignItems: 'center',
justifyContent: 'center',
gap: '3px',
textDecoration: 'none',
fontSize: 'var(--text-label-size, 13px)',
fontWeight: 400,
lineHeight: 'var(--text-label-line-height, 1.4)',
fontFamily: 'var(--font-family-base)',
color: 'var(--color-text-muted)',
minHeight: '44px',
borderBottom: '2px solid transparent',
transition: 'color 0.1s ease, border-color 0.1s ease',
};
const tabActiveOverride: React.CSSProperties = {
color: 'var(--color-member-0)',
borderBottom: '2px solid var(--color-member-0)',
};
```
---
### `apps/pwa/src/styles/tokens.css` — selector restructure + add `--bottom-chrome-h`
**Analog:** self (selector-only change)
**Current structure:**
```css
:root {
/* all tokens */
}
```
**After restructure — combined selector, no value changes:**
```css
:root,
[data-theme="light"] {
/* All existing :root declarations move here verbatim */
/* Add new token at the top of the spacing group: */
--bottom-chrome-h: calc(56px + env(safe-area-inset-bottom, 0px));
/* ...all existing tokens unchanged... */
/* Schedule-X overrides stay INSIDE this same rule block (critical — see pitfall 3) */
--sx-color-primary: var(--color-member-0);
/* etc. */
}
/* Dark theme stub — values intentionally absent (Phase 17 groundwork only).
Phase 999.20 fills these values and wires prefers-color-scheme. */
/* [data-theme="dark"] { ... } */
```
**Key constraint:** `--sx-color-*` overrides must remain inside the same combined rule block — do NOT split into a separate selector.
---
### `apps/pwa/src/components/BrandSlot.tsx` — swap placeholder div for `<img>`
**Analog:** self, lines 2950 (the placeholder div to replace)
**Current placeholder (lines 2950):**
```tsx
{/* Phase 17 replaces this div with <img src="..." alt="" /> */}
<div
aria-hidden="true"
style={{
width: 'var(--brand-logo-size, 48px)',
height: 'var(--brand-logo-size, 48px)',
borderRadius: 'var(--brand-logo-border-radius, 50%)',
background: 'var(--brand-logo-bg, var(--color-member-0, #4a90d9))',
color: 'var(--brand-logo-text, #ffffff)',
display: 'flex',
alignItems: 'center',
justifyContent: 'center',
margin: '0 auto var(--space-2, 8px)',
fontSize: 'var(--text-display-size, 24px)',
fontWeight: 600,
fontFamily: 'var(--font-family-base)',
flexShrink: 0,
aspectRatio: '1 / 1',
}}
>
FS
</div>
```
**After swap — keep same token surface, swap element:**
```tsx
<img
src="/logo.svg"
alt=""
aria-hidden="true"
style={{
width: 'var(--brand-logo-size, 48px)',
height: 'var(--brand-logo-size, 48px)',
borderRadius: 'var(--brand-logo-border-radius)',
margin: '0 auto var(--space-2, 8px)',
display: 'block',
aspectRatio: '1 / 1',
objectFit: 'contain',
flexShrink: 0,
}}
/>
```
**`--brand-logo-bg` is no longer applied** (no background div). Update `--brand-logo-border-radius` in tokens.css from `50%` to the checkpoint-determined value (likely `12px` for warm/rounded brief or `0` if the SVG draws its own shape).
---
### `apps/pwa/index.html` — add favicon links
**Analog:** self (additive changes only)
**Current state (one apple-touch-icon link, no favicon links):**
```html
<meta name="theme-color" content="#4A90D9" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />
```
**After Phase 17:**
```html
<meta name="theme-color" content="{CHECKPOINT_ACCENT_HEX}" />
<link rel="icon" href="/favicon.svg" type="image/svg+xml" />
<link rel="icon" href="/favicon.ico" sizes="any" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" sizes="180x180" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="default" />
<meta name="apple-mobile-web-app-title" content="FamilySync" />
```
Order matters: SVG first (modern browsers), ICO second (legacy fallback). `{CHECKPOINT_ACCENT_HEX}` = `#4A90D9` (default) or warm variant pending checkpoint.
---
### `apps/pwa/vite.config.ts` — fix maskable icon + add `icon-maskable-512.png`
**Analog:** self, lines 3842
**Current defective icons array (lines 3842):**
```ts
icons: [
{ src: '/icon-192.png', sizes: '192x192', type: 'image/png' },
{ src: '/icon-512.png', sizes: '512x512', type: 'image/png' },
{ src: '/icon-512.png', sizes: '512x512', type: 'image/png', purpose: 'maskable' }, // ← DEFECT: same file
],
```
**After fix — separate maskable file:**
```ts
icons: [
{ src: '/icon-192.png', sizes: '192x192', type: 'image/png' },
{ src: '/icon-512.png', sizes: '512x512', type: 'image/png' },
{ src: '/icon-maskable-512.png', sizes: '512x512', type: 'image/png', purpose: 'maskable' },
],
```
Also update `theme_color` (line 33) to match checkpoint accent: `'#4A90D9'` default.
---
### `apps/pwa/src/components/SettingsSheet.tsx` — add logout row + desktop centering
**Analog:** self
**Current sheet outer `<div role="dialog">` (lines 184202) — the centering defect site:**
```tsx
// SettingsSheet.tsx lines 184-202 — currently bottom-only positioning
<div
role="dialog"
aria-modal="true"
aria-label="Settings"
style={{
position: 'fixed',
bottom: 0,
left: 0,
right: 0,
background: 'var(--color-surface-raised, #ffffff)',
borderRadius: '12px 12px 0 0',
boxShadow: '0 -4px 24px rgba(0,0,0,0.15)',
padding: 'var(--space-6, 24px)',
zIndex: 301,
fontFamily: 'var(--font-family-base, system-ui, sans-serif)',
maxWidth: '480px',
margin: '0 auto',
// ← Desktop renders this bottom-center (defect D-09)
}}
>
```
**After fix — phone/desktop style branch:**
```tsx
// isPhone() from App.tsx pattern (same function defined identically in BottomTabBar.tsx)
const phone = window.matchMedia('(max-width: 767px)').matches;
<div
role="dialog"
aria-modal="true"
aria-label="Settings"
style={
phone
? {
// Phone: unchanged bottom-sheet
position: 'fixed',
bottom: 0,
left: 0,
right: 0,
background: 'var(--color-surface-raised, #ffffff)',
borderRadius: '12px 12px 0 0',
boxShadow: '0 -4px 24px rgba(0,0,0,0.15)',
padding: 'var(--space-6, 24px)',
zIndex: 301,
fontFamily: 'var(--font-family-base, system-ui, sans-serif)',
}
: {
// Desktop: centered modal
position: 'fixed',
top: '50%',
left: '50%',
transform: 'translate(-50%, -50%)',
maxWidth: '480px',
width: 'calc(100% - var(--space-8, 32px))',
maxHeight: 'calc(100dvh - var(--space-8, 32px))',
overflowY: 'auto',
background: 'var(--color-surface-raised, #ffffff)',
borderRadius: '12px',
boxShadow: '0 8px 32px rgba(0,0,0,0.18)',
padding: 'var(--space-6, 24px)',
zIndex: 301,
fontFamily: 'var(--font-family-base, system-ui, sans-serif)',
}
}
>
```
**This exact phone/desktop pattern applies to ALL sheets:**
- `SettingsSheet` outer `<div role="dialog">` (lines 184202)
- `ChangePasswordSheet` outer `<div role="dialog">` (lines 598616)
- `LinkOidcSheet` outer `<div role="dialog">` (lines 894909)
- `AdminPage.ResetPasswordSheet` outer `<div role="dialog">` (lines 12621280)
- `CredentialSheet` (separate file — apply same branch)
**Logout row pattern — add after the Account section (after line 437 close tag, before the backdrop close):**
```tsx
{/* Sign out — bottom of sheet, after all other sections */}
<div
style={{
height: '1px',
background: 'var(--color-border-subtle, var(--color-border))',
margin: 'var(--space-4, 16px) 0',
}}
/>
<button
type="button"
onClick={handleSignOut}
aria-label="Sign out"
style={{
display: 'flex',
alignItems: 'center',
gap: 'var(--space-2, 8px)',
width: '100%',
minHeight: '44px',
background: 'none',
border: 'none',
cursor: 'pointer',
padding: 'var(--space-2, 8px) 0',
fontSize: 'var(--text-body-size, 15px)',
fontWeight: 400,
color: 'var(--color-destructive, #dc2626)',
fontFamily: 'var(--font-family-base)',
textAlign: 'left',
}}
>
<LogOut size={16} aria-hidden="true" />
Sign out
</button>
```
**handleSignOut function — try/catch with navigate in both branches (pitfall 4):**
```ts
// Import: import { LogOut } from 'lucide-react'; (add to existing X, Bell, AlertCircle, Loader2)
// Import: import { fetchLocalLogout } from '../api/client.js'; (add to existing fetchMe, etc.)
// Import: import { useNavigate } from 'react-router'; (or use window.location.replace)
async function handleSignOut() {
try {
await fetchLocalLogout();
} catch {
// Fire-and-best-effort: navigate regardless of whether the API call succeeded
}
// Always navigate — server-side cookie was cleared (or already expired)
navigate('/login');
}
```
**Existing section divider pattern analog (lines 372376) — same style for logout separator:**
```tsx
<div
style={{
height: '1px',
background: 'var(--color-border-subtle, var(--color-border))',
margin: 'var(--space-4, 16px) 0',
}}
/>
```
---
### `apps/pwa/src/routes/AdminPage.tsx` — success toasts + two-tab navigation
**Analog:** self + `SyncStateToast.tsx`
**Existing `createMemberMutation.onSuccess` (lines 213221) — hook point for toast:**
```ts
onSuccess: () => {
// Clear form + refresh member list
setCreateDisplayName('');
setCreateUsername('');
setCreatePassword('');
setCreateConfirmPassword('');
setCreateError(null);
void queryClient.invalidateQueries({ queryKey: ['admin', 'members'] });
void queryClient.invalidateQueries({ queryKey: ['me'] });
// ← ADD: setToast('Member added.')
},
```
**Existing `resetMutation.onSuccess` (lines 12301232) — hook point for toast:**
```ts
onSuccess: () => {
handleClose();
// ← ADD: setToast('Password reset.') — must propagate up from ResetPasswordSheet
},
```
**Toast state pattern — inline in AdminPage (no new component needed; single use):**
```ts
// Local state — add at top of AdminPage()
const [toast, setToast] = useState<string | null>(null);
// Auto-dismiss after 3 seconds — same useEffect pattern as SyncStateToast lines 72-79
useEffect(() => {
if (!toast) return;
const timer = setTimeout(() => setToast(null), 3000);
return () => clearTimeout(timer);
}, [toast]);
```
**Toast render — copy visual structure from SyncStateToast.tsx lines 159189:**
```tsx
// SyncStateToast.tsx lines 159-189 — extract the wrapper div pattern
{toast && (
<div
role="status"
aria-live="polite"
aria-atomic="true"
style={{
position: 'fixed',
bottom: phone
? 'calc(var(--bottom-chrome-h) + var(--space-4))'
: 'var(--space-6)',
left: '50%',
transform: 'translateX(-50%)',
zIndex: 300,
background: 'var(--color-surface-raised, #ffffff)',
border: '1px solid var(--color-border)',
borderRadius: 'var(--space-2, 8px)',
boxShadow: '0 2px 8px rgba(0,0,0,0.12)',
padding: 'var(--space-3, 12px) var(--space-4, 16px)',
display: 'flex',
alignItems: 'center',
gap: 'var(--space-2, 8px)',
fontSize: 'var(--text-label-size, 13px)',
fontWeight: 'var(--text-label-weight, 400)',
lineHeight: 'var(--text-label-line-height, 1.4)',
fontFamily: 'var(--font-family-base)',
color: 'var(--color-text-primary)',
whiteSpace: 'nowrap',
maxWidth: '90vw',
}}
>
<CheckCircle size={16} aria-hidden="true" style={{ color: 'var(--color-member-0)', flexShrink: 0 }} />
<span>{toast}</span>
</div>
)}
```
Note: `CheckCircle` is already imported in AdminPage.tsx line 28. `phone` constant needs adding (use `isPhone()` or inline `window.matchMedia`).
**Two-tab strip pattern — add above MEMBERS section (after `<h1>Admin Settings</h1>`):**
```tsx
// Local state — add at top of AdminPage()
const [activeTab, setActiveTab] = useState<'members' | 'settings'>('members');
// Keyboard nav for roving tabindex
function handleTabKeyDown(e: React.KeyboardEvent, current: 'members' | 'settings') {
if (e.key === 'ArrowRight') {
e.preventDefault();
const next = current === 'members' ? 'settings' : 'members';
setActiveTab(next);
(e.currentTarget.parentElement?.querySelector(`[id="admin-tab-${next}"]`) as HTMLElement)?.focus();
} else if (e.key === 'ArrowLeft') {
e.preventDefault();
const prev = current === 'settings' ? 'members' : 'settings';
setActiveTab(prev);
(e.currentTarget.parentElement?.querySelector(`[id="admin-tab-${prev}"]`) as HTMLElement)?.focus();
}
}
// Tab strip render
<div
role="tablist"
style={{
display: 'flex',
borderBottom: '1px solid var(--color-border-subtle, var(--color-border))',
marginBottom: 'var(--space-6, 24px)',
}}
>
{(['members', 'settings'] as const).map((id) => (
<button
key={id}
role="tab"
id={`admin-tab-${id}`}
aria-selected={activeTab === id}
aria-controls={`admin-panel-${id}`}
tabIndex={activeTab === id ? 0 : -1}
onClick={() => setActiveTab(id)}
onKeyDown={(e) => handleTabKeyDown(e, id)}
style={{
background: 'none',
border: 'none',
cursor: 'pointer',
padding: 'var(--space-3, 12px) var(--space-4, 16px)',
minHeight: '44px',
fontSize: 'var(--text-label-size, 13px)',
fontWeight: activeTab === id ? 600 : 400,
color: activeTab === id ? 'var(--color-text-primary)' : 'var(--color-text-secondary)',
borderBottom: activeTab === id ? '2px solid var(--color-member-0)' : '2px solid transparent',
transition: 'color 0.1s ease, border-color 0.1s ease',
fontFamily: 'var(--font-family-base)',
}}
>
{id === 'members' ? 'Members & Accounts' : 'Settings'}
</button>
))}
</div>
{/* Tab panels */}
<div
role="tabpanel"
id="admin-panel-members"
aria-labelledby="admin-tab-members"
tabIndex={0}
hidden={activeTab !== 'members'}
>
{/* MEMBERS section + LOCAL ACCOUNTS section */}
</div>
<div
role="tabpanel"
id="admin-panel-settings"
aria-labelledby="admin-tab-settings"
tabIndex={0}
hidden={activeTab !== 'settings'}
>
{/* SHARED CALENDAR section + TIMEZONE section */}
</div>
```
**Existing `sectionLabelStyle` (lines 4451) — reuse unchanged inside tab panels:**
```ts
const sectionLabelStyle: React.CSSProperties = {
fontSize: 'var(--text-label-size, 13px)',
fontWeight: 600,
color: 'var(--color-text-muted)',
textTransform: 'uppercase',
letterSpacing: '0.06em',
marginBottom: 'var(--space-2, 8px)',
};
```
---
### `apps/pwa/e2e/layout.spec.ts` — add FAB/BottomTabBar overlap assertion
**Analog:** self, lines 3060 (existing test structure pattern)
**Existing test structure to follow (lines 31-60):**
```ts
test.describe('Rule 1/3/4 — BottomTabBar tap targets and in-viewport position', () => {
test.beforeEach(async ({ page }) => {
await page.goto('/calendar');
});
test('Calendar tab meets 44×44px touch-target minimum (Rule 1)', async ({ page }) => {
const nav = page.getByRole('navigation', { name: 'Main navigation' });
const calTab = nav.getByRole('link', { name: 'Calendar' });
const box = await calTab.boundingBox();
expect(box, 'Calendar tab bounding box must not be null').not.toBeNull();
expect(box!.width, 'Calendar tab width ≥ 44px').toBeGreaterThanOrEqual(44);
expect(box!.height, 'Calendar tab height ≥ 44px').toBeGreaterThanOrEqual(44);
});
```
**New overlap assertion to add:**
```ts
test('New Event FAB does not overlap BottomTabBar (A — phone only)', async ({ page }, testInfo) => {
test.skip(testInfo.project.name === 'desktop', 'Phone-only assertion');
await page.goto('/calendar');
const fab = page.getByRole('button', { name: 'New Event' });
const nav = page.getByRole('navigation', { name: 'Main navigation' });
const fabBox = await fab.boundingBox();
const navBox = await nav.boundingBox();
expect(fabBox, 'FAB bounding box must not be null').not.toBeNull();
expect(navBox, 'BottomTabBar bounding box must not be null').not.toBeNull();
// FAB bottom edge must be at or above the BottomTabBar top edge
expect(fabBox!.y + fabBox!.height).toBeLessThanOrEqual(navBox!.y);
});
```
---
### `apps/pwa/e2e/admin.spec.ts` (new file)
**Analog:** `apps/pwa/e2e/layout.spec.ts` — copy file header pattern, test.describe structure, page.goto pattern
**File header + structure pattern (layout.spec.ts lines 127):**
```ts
/**
* admin.spec.ts — TEST-XX
*
* Admin page UI assertions: two-tab ARIA pattern, success toasts, sheet centering.
* ...
*
* Runs on all three device profiles unless skipped via testInfo.project.name.
*/
import { test, expect } from '@playwright/test';
test.describe('Admin tab strip — ARIA tabs pattern (D-10)', () => {
test.beforeEach(async ({ page }) => {
// Note: requires an admin session — playwright.config.ts storageState for admin
await page.goto('/admin');
});
test('Tab strip has correct ARIA roles', async ({ page }) => {
await expect(page.getByRole('tablist')).toBeVisible();
await expect(page.getByRole('tab', { name: 'Members & Accounts' })).toBeVisible();
await expect(page.getByRole('tab', { name: 'Settings' })).toBeVisible();
});
test('ArrowRight switches to Settings tab', async ({ page }) => {
const membersTab = page.getByRole('tab', { name: 'Members & Accounts' });
await membersTab.focus();
await page.keyboard.press('ArrowRight');
await expect(page.getByRole('tab', { name: 'Settings' })).toHaveAttribute('aria-selected', 'true');
});
});
```

## Shared Patterns
### Phone/Desktop Breakpoint
**Source:** `apps/pwa/src/components/BottomTabBar.tsx` lines 2325; `apps/pwa/src/App.tsx` line 64
**Apply to:** All sheet centering fixes (SettingsSheet, ChangePasswordSheet, LinkOidcSheet, ResetPasswordSheet, CredentialSheet), admin toast positioning, admin tab strip phone layout check
```ts
// Identical function defined in BottomTabBar.tsx, App.tsx, CalendarShell.tsx
function isPhone(): boolean {
return typeof window !== 'undefined' && window.matchMedia('(max-width: 767px)').matches;
}
// Or inline: window.matchMedia('(max-width: 767px)').matches
```
### Sheet/Dialog Pattern
**Source:** `apps/pwa/src/components/SettingsSheet.tsx` lines 170202 (backdrop + dialog wrapper)
**Apply to:** All sheets that need desktop-centering fix
```tsx
{/* Backdrop — unchanged across all sheets */}
<div
onClick={onClose}
aria-hidden="true"
style={{

background: 'var(--color-overlay, rgba(0,0,0,0.32))',
zIndex: 300, // or appropriate z-index per stacking context
}}

### Section Divider Pattern
**Source:** `apps/pwa/src/components/SettingsSheet.tsx` lines 372376
**Apply to:** Logout row separator in SettingsSheet
```tsx
<div
style={{
height: '1px',
background: 'var(--color-border-subtle, var(--color-border))',
margin: 'var(--space-4, 16px) 0',
}}
/>
```
### Mutation + Toast Pattern
**Source:** `apps/pwa/src/routes/AdminPage.tsx` lines 197235 (`createMemberMutation`), `apps/pwa/src/components/SyncStateToast.tsx` lines 7279 (auto-dismiss), lines 159189 (toast render)
**Apply to:** AdminPage create-member and reset-password success feedback
Auto-dismiss pattern from SyncStateToast (lines 7279):
```ts
useEffect(() => {
if (status !== 'done') return; // adapt: if (!toast) return;
const timer = setTimeout(() => {
setLastSyncedUid(null); // adapt: setToast(null)
}, 2000); // use 3000ms for admin toasts per UI-SPEC
return () => clearTimeout(timer);
}, [status, setLastSyncedUid]);
```
### Accessible Button Row Pattern
**Source:** `apps/pwa/src/components/SettingsSheet.tsx` lines 390410 (Change password button row)
**Apply to:** Logout button in SettingsSheet
```tsx
<button
type="button"
onClick={...}
style={{
display: 'flex',
alignItems: 'center',
width: '100%',
minHeight: '44px', // WCAG tap target
background: 'none',
border: 'none',
cursor: 'pointer',
padding: 'var(--space-2, 8px) 0',
fontSize: 'var(--text-body-size, 15px)',
fontWeight: 400,
color: 'var(--color-text-primary, #111318)', // logout: var(--color-destructive)
fontFamily: 'var(--font-family-base)',
textAlign: 'left',
}}
>
...label
</button>
```

## No Analog Found
| File | Role | Data Flow | Reason |
|------|------|-----------|--------|
| `apps/pwa/public/logo.svg` | asset | transform | New AI-generated SVG logo — no existing brand mark in codebase |
| `apps/pwa/public/favicon.svg`, `favicon.ico`, `icon-maskable-512.png` | asset | transform | New generated assets — none exist in `public/` yet |
| `apps/pwa/pwa-assets.config.ts` | config | transform | New `@vite-pwa/assets-generator` config — no prior asset-generation config in repo |

## Critical Pitfalls (for Planner)
1. **Maskable icon must be a separate file.** `icon-maskable-512.png` is a distinct generated asset with safe-zone padding — the defect is reusing `icon-512.png` for the maskable purpose. Fix by generating `icon-maskable-512.png` via `@vite-pwa/assets-generator`.
2. **`paddingBottom` in `contentStyle` is phone-only.** The `...(phone ? {...} : {})` spread pattern (from outerStyle at App.tsx lines 144152) ensures desktop gets no extra bottom padding.
3. **`--sx-color-*` overrides must stay inside the combined `tokens.css` rule block.** Do not split them to a separate selector — they must override the `@schedule-x/theme-default` values by staying in the same specificity context.
4. **`fetchLocalLogout` error must not prevent navigation.** Wrap in try/catch and call `navigate('/login')` in both branches — fire-and-best-effort semantics per UI-SPEC §D-07.
5. **`--brand-logo-border-radius` update required after logo approval.** The current `50%` value (circle) clips an SVG logo that draws its own shape. Update to `12px` (warm/rounded) or `0` (if SVG has own border-radius) at the checkpoint — before wiring.
6. **Admin tab state is not URL-persisted.** Tab state is `useState` only — navigating away and back resets to Tab 1 ("Members & Accounts"). This is intentional per UI-SPEC §D-10.
