[pending-judge] feat(DC-168): calendar widget UX + theming — "No upcoming appointments" state, month grid with highlighted appointment days, theme-correct styling
Owner directives (2026-10-10/11, verbatim in brief): show "no upcoming
appointments" when empty; show a month calendar with days and times
highlighted when there are events; stylize to fit every theme; keep the
widget weather-widget-sized.
Changes (status/ frontend + tests):
- status/js/calendar-widget.js: rewritten render path — chip states ("No
upcoming appointments" / next appointment with highlighted when-span),
month grid modal (cal-grid + prev/next nav, appointment days highlighted,
per-event time dots), upcoming list with day/time emphasis, 60-day+
month-following fetch with window-authoritative event merge (via
calendar-cache.js), forced refresh on periodic tick + source mutations,
local escapeHtml (was an undefined global).
- status/js/calendar-cache.js (new): uid+start-keyed event cache; fetched
window is authoritative for entries starting inside it (deletions and
reschedules propagate), entries outside survive. Dual export (module +
window) for tests and browser bundle.
- status/build.js: calendar-cache.js bundled before calendar-widget.js.
- status/css/dashboard.css: DC-168 block — chip states, month grid, day
highlight states, dots, list/source rows, universal light-bg contrast
rules (color-mix; WCAG >= 4.5:1 verified for all 10 builtin themes,
worst 4.60:1 ocean) + light-surface rules.
- Tests (20 total in __tests__/calendar): 9-test ns suite (extraction incl.
mixed docs, empty multistatus, namespace-aware fixture validation,
undeclared-prefix rejection both quote styles, positive declared-attr),
4-test dc168-cache contract (merge, duplicate suppression, recurring
uid+start, window-authoritative removal, cross-window survival, ended-
exclusion), 4-test widget contract + 2-test integration/gap (repo root
derived from __dirname; smoke takes argv/env; zero hardcoded /root paths).
Existing suites pass unmodified; eslint 0 errors on touched files.
