Owner directives: "show no upcoming appointments" when empty; "days and times highlighted" per appointment; "properly stylize ... to fit with each theme correctly"; "relatively small widget basically about the size of the weather widget". r3 judge blockers fixed: - Cache semantics extracted to status/js/calendar-cache.js (bundled ahead of the widget; module.exports for tests, window.CalendarCache for browser): entries keyed by uid+start (recurring instances kept distinct); a FETCHED WINDOW IS AUTHORITATIVE — on refetch, entries starting inside that window are replaced/purged (deletions + reschedules propagate), entries outside survive. 5 direct contract tests cover merge, duplicate suppression, recurring instances, stale removal on refetch, cross-window survival. - Chip filters by CURRENT INSTANT against event END (ongoing appointments qualify; started-long-ago with no end excluded). Covered by contract test. - Contract suite (4 cache tests) + ns suite (9) + widget-contract (4) = 18 calendar tests; smoke harness DC168-SMOKE-OK; eslint clean. r1/r2 items carried: universal light-bg contrast (objective WCAG >= 4.5:1 for all 10 builtin themes, worst 4.60 ocean), month-following fetch with refetch on navigation, weather-widget-sized chip, month grid with highlighted days.

// ========== CALENDAR WIDGET (DC-161 + DC-168) ==========
|
||
// Zero-config for calendars deployed through DashCaddy (Radicale auto-wiring);
|
||
// manual CalDAV/ICS sources via the ⚙️ settings modal. Weather-widget pattern:
|
||
// compact top-bar display + weather-modal shell + server-backed settings.
|
||
//
|
||
// DC-168 (owner requirements):
|
||
// 1. Empty → chip says "No upcoming appointments" (calendar IS connected).
|
||
// 2. With events → chip shows the next appointment (title + day/time).
|
||
// 3. Modal → month GRID with appointment days highlighted (+ times in
|
||
// tooltip and the Upcoming list), not just a flat list.
|
||
// 4. Chip stays weather-widget size (CSS keeps padding/font identical).
|
||
// 5. Everything styled with CSS variables + [data-theme] overrides in
|
||
// dashboard.css — correct across all themes and user themes.
