/*
 * apps/support — 2026 dark-admin-console redesign (27 Sep 2026).
 *
 * REPLACES T-884's cream/gold/red styling entirely, per Mahdi's explicit
 * direction (docs/figma-prompt-apps-support.md): this internal tool gets
 * its own distinct visual identity, separate from the member-facing
 * brand — no cream, gold or red as primary colors here. Dark sidebar +
 * light content, modern geometric-leaning sans, thin 1px borders + soft
 * low-opacity shadows over heavy drop-shadows, modest 6-10px radii.
 * Structure picked from 3 real built comparisons (docs/helper-inbox.md
 * I-8005) — this is "Variant C": KPI cards + a "Needs attention"
 * highlights rail, breakdown tables full-width below.
 *
 * Accent color, D-85 (27 Sep 2026): originally shipped with a one-off
 * indigo (#4f46e5) as this app's own distinct accent. Retired same day
 * in favor of the shared navy/gold pair (#1B4F82/#C9A227) already proven
 * in apps/console + apps/web, so all three apps read as one brand.
 *
 * Served via the same `GET /styles.css` static route T-884 added — see
 * that route's own comment in server.mjs, unchanged by this task.
 *
 * FONT NOTE, same constraint as T-884: the CSP here is `default-src
 * 'none'` with no `font-src` at all, so Inter/Geist cannot be fetched
 * externally without a CSP change this visual-only task doesn't own.
 * Falls back to the most geometric/grotesk-leaning system stack
 * available (Segoe UI / SF Pro / system-ui) — documented as a deliberate
 * choice, easy to revisit as its own separately-reviewed change if
 * self-hosting a real webfont is wanted later.
