The per-family remap (shared, member-1..4) only fills all-day pills whose
Schedule-X colorName is registered. Member calendars absent from the current
/api/me members list fall back to Schedule-X's built-in primary family, which
was not remapped — so those all-day events degraded to the light tint. Remap
--sx-color-primary-container as well so all-day pills stay solid in the
fallback case too (production member-N calendars already covered).
