/**
 * Elevate LMS — server-rendered surface styles.
 *
 * FLAT PROFESSIONAL design, matching the React webapp/dashboard (the `--pge-*`
 * token system in src/styles.css): white cards, slate hairline borders, subtle
 * shadows, indigo primary, Outfit/Inter type. (The legacy neumorphic look was
 * replaced per design review — the student LMS now renders as React tabs inside
 * the real dashboard; these styles cover the parent portal and any SSR
 * fallback so every Elevate surface looks like the app.)
 *
 * Scoped under .pge-elevate. The `--pgl-*` set below is Elevate's LOCAL
 * vocabulary: each one aliases a global `--pge-*` token but carries a hard
 * fallback, so this file still renders on surfaces where src/styles.css was
 * never enqueued (the parent portal, any SSR fallback). Enqueued only on LMS
 * surfaces.
 *
 * The local set is prefixed `--pgl-` rather than `--pge-` for a mechanical
 * reason: the globals used to be `--tb-*`, so prefix alone told the two layers
 * apart. Once the testbook namespace was retired and the globals became
 * `--pge-*`, every alias here read `--pge-ui-bg: var(--pge-ui-bg, …)` — a custom
 * property referencing itself, which CSS treats as invalid at computed-value
 * time. The whole scoped palette would have silently evaluated to nothing.
