/*
 * OrbitAIO "Liquid Glass" — design tokens + utilities for the vanilla
 * static pages (dashboard.html, chooser.html; index.html follows in WP3).
 *
 * Ported from frontend/src/theme/orbit-glass.css:37-247 — the Tailwind
 * @theme block there becomes a plain :root block here (same property names,
 * same values), since these pages have no Tailwind pipeline. That file's own
 * comment at :199-206 already anticipated this: "Kept as plain classes
 * rather than @utility so they also work in the non-Tailwind static pages
 * (api/static) later in Phase 2."
 *
 * Each page keeps its OWN pre-existing --neon-blue/--dark-bg/--card-bg/...
 * variables (same hex values, different names) for its existing rules —
 * this file adds the NEW --color-, --radius- and --glass- prefixed names
 * alongside them rather than renaming anything, so it is purely additive.
 *
 * ⚠️ ROOT-PAINTING RULE (read before touching the ambient layer or adding a
 * full-bleed background anywhere): backdrop-filter has nothing to blur over
 * a flat fill, so the ambient gradient below is not decoration — without it
 * every .glass-card renders as a plain dark rectangle. And only `html` (the
 * true root element) may hold the page's opaque background. Per CSS2.1
 * Appendix E, a negative-z-index child of `body` (the ambient layer) paints
 * in step 2 of body's stacking context, but body's OWN background paints in
 * step 3 — so if `body` (or any full-bleed wrapper) has an opaque
 * background, it paints OVER the ambient layer and hides it. This is not
 * theoretical: it is exactly what happened in the Electron app the first
 * time this pattern was introduced (tokens correct, ambient invisible,
 * because body AND #root both painted over body::before) — see
 * CLAUDE-orbitaio-todo.md §2. Fixed there by moving the opaque background to
 * `html` and leaving body transparent; do the same for every future
 * full-bleed element in these pages.
