/*
 * glass.css — Glass design-language surface vocabulary (shared)
 * ============================================================
 * Load AFTER global.css in index.html and worker/index.html.
 *
 * These are the prototype's glass surfaces (glass-dashboard/styles.css),
 * extracted and rewritten to consume THIS app's existing three-tier tokens
 * (design-tokens.css + variables.css) — NOT a parallel r-x / sp-x / fg token set
 * (Design Reference §8.3). Purple/gold tints derive from the Tier 2 brand
 * tokens via color-mix, so a white-label rebrand recolours the glass too.
 *
 * ROLLOUT STATUS (Slice 1 phase 2b-A): these classes are ADDITIVE and, apart
 * from `.icon`, currently UNCONSUMED — pages/components adopt them in the later
 * per-surface adoption slices. This file deliberately does NOT redefine the
 * existing shared `.btn`/`.btn-primary`/`.card` (global.css owns those); it only
 * adds NEW glass variants (`.glass-card`, `.btn-secondary`, `.btn-small`, …) so
 * loading it changes no existing element.

   A bare `1fr 1fr` grid cannot do this: grid items default to min-width:auto,
   and input[type=date] has a ~170px intrinsic minimum (its dd/mm/yyyy fields +
   picker icon), so on a 360px phone each 1fr track blew past its share and the
   second field ran off the card — the leave From/To overlap Adam hit.
   The floor is that intrinsic width, so two-up survives only where two genuinely
   fit; min(100%, …) keeps the floor itself from overflowing a narrow parent, and
   min-width:0 on the children stops any other wide control blowing a track out.
   Spacing matches the .form-group rhythm so a row and a field sit evenly. */

/* ── Modal chrome (Modal.js re-skin — rollout Slice 4) ───────────────────────
   Chrome only. The PRESERVED contract: ids, open/close/backdrop/✕ semantics,
   display toggling from JS, NO Escape handler, NO focus trap (ThemePrompt.js
   scopes its own Escape). Bodies are page-owned HTML strings; they adopt the
   form vocabulary in their page slices.
   The panel is deliberately MORE opaque than a glass-card (color-mix off the
   theme's solid card colour): body copy and form controls sit on it over an
   unpredictable dimmed page, so readability wins over translucency — the
   backdrop supplies the glass depth.
   NOTE: the panel's backdrop-filter makes it the containing block for
   position:fixed descendants — fixed overlays launched from a modal body must
   append to document.body (all current ones do) or they will be trapped and
   scroll-clipped inside the panel. */
