6/* ── SHIROFES OS — Standalone version-polling + hard-refresh helper ─────────
7 *
8 * v135.105 — extracted from shared/state.js so pages that don't load state.js
9 * (the "exception pages" — post-event, mc, mc-script, cast, crew, portal,
10 * register, register-cast, reflect, debrief, timetable, rundown, index) get
11 * stale-tab detection consistent with admin/staff/kiosk/etc.
12 *
13 * Pre-v135.105 only `state.js`-loading pages + dj.html + live.html (rolled
14 * their own inline pollers) had the toast. mc-script.html during a live
15 * SHIROFES set could sit on stale code if the operator left a tab open
16 * across a hotfix deploy. This module closes that gap without forcing
17 * `state.js` onto pages that intentionally don't carry it (cf. EXECUTION_
18 * STATE.md "Exception-page architecture variance is intentional").
19 *
20 * Contract:
21 *   - Idempotent: `window.__versionPollActive` guards re-entry. State.js's
22 *     `setupVersionPolling` (still present for back-compat) checks the same
23 *     flag and no-ops when this module has already booted.
24 *   - Self-bootstraps: first poll seeds the local-version baseline from
25 *     `window.SHIROFES_APP_VERSION` if present (set by firebase-config.js
26 *     on script-tag-loaded pages), else from the first version.json read
27 *     itself. Subsequent polls compare against the seeded baseline.
28 *     This makes the module work uniformly on script-tag pages (admin/
29 *     staff/etc.) AND on ES-module pages (mc.html) that don't load
30 *     firebase-config.js synchronously.
31 *   - Polls `version.json` 30s after load, then every 5min.
32 *   - Banner is identical to state.js's (same id `versionUpdateBanner`, same
33 *     hard-refresh CTA) so operators see one consistent UI across all pages.
34 *
35 * Hard-refresh exposed at `window.__shirofesHardRefresh` — pages that already
36 * defined it (state.js) keep theirs; this module's definition only attaches
37 * if absent.
38 * ──────────────────────────────────────────────────────────────────────── */
