 - [Phase ?]: resolveUserId helper uses any type to avoid Hono context generic complexity — internal helper only
 - [Phase ?]: Write endpoints enqueue-only (calendarOutbox) with 202 optimistic-accept; no Fastmail call in routes (D-12/D-05)
 - [Phase ?]: GET /writable-calendars is authoritative D-03 writable-set endpoint: WHERE userId=currentUser.id OR isShared=1
+- [Phase ?]: D-03-07-icons: PWA icons generated via pure Node.js (zlib/Buffer) when ImageMagick/sharp unavailable; placeholder art; operator can replace in public/ without code changes
+- [Phase ?]: D-03-07-layout: InstallPrompt desktop layout wraps CalendarContent in flex-column div so banner appears above calendar grid
