/* ============================================================================
 * site/styles/tokens.css — runtime token subset
 * Cascade position 1 of 5 (tokens → base → components → sections → responsive).
 *
 * PUBLISH ROOT: `site/` is the only publishable directory in this repository.
 * Nothing under `site/` may reference, import, link to, or embed anything from
 * the private research directories, the repository-root legacy page, the older
 * landing seeds, or the raw design deliveries. Two accepted repository-root
 * packages feed this tree — `design-system/` (tokens and contracts) and
 * `landing-content/` (authored copy, claim IDs, fixture values, asset
 * provenance) — and both feed it by *copy at authoring time*, never by a
 * runtime import. This file in particular takes its values from
 * `design-system/` alone; `landing-content/` carries no token. All paths inside
 * `site/` are relative.
 *
 * ---------------------------------------------------------------------------
 * SOLE TOKEN CARRIER
 * ---------------------------------------------------------------------------
 * This is the ONLY file under `site/` that carries token *values*. Every other
 * stylesheet, and every inline style, must reference these roles through
 * `var(--role)` and must never restate a literal that has a token. The three
 * media-query width literals in `responsive.css` are the single documented
 * exception, for the reason recorded there.
 *
 * ---------------------------------------------------------------------------
 * PROVENANCE AND TRACE (acceptance criterion 4)
 * ---------------------------------------------------------------------------
 * Source: `design-system/tokens.css` v2.0.0 (2026-08-01), the accepted
 * normalized GeoSense launch system. Copied verbatim, role name and value
 * identical, no value re-derived and no new value introduced here.
 *
 * The accepted package declares 154 roles with 1:1 name-and-value parity
 * between `design-system/tokens.css` and `design-system/tokens.json`
 * (leaf `cssVar`). This runtime subset ships **147** of them.
 *
 * Every role below traces to an accepted `design-system/tokens.json` group,
 * named in the section comment that introduces it, and to the identically
 * named custom property in `design-system/tokens.css`.
 *
 * EXCLUDED — 7 roles, the whole `tokens.json → breakpoint` group
 * (`--bp-floor`, `--bp-mobile`, `--bp-tablet`, `--bp-desktop-sm`,
 * `--bp-desktop`, `--bp-reference`, `--bp-ceiling`).
 * They are documentation values, not runtime values: `design-system/tokens.css`
 * labels them as such in-source, and `design-system/RESPONSIVE.md` states that
 * CSS media queries cannot reference custom properties, so a breakpoint token
 * can never be consumed by the runtime that needs it. Shipping them would put
 * seven unreadable values in every visitor's stylesheet. `responsive.css`
 * records the literal-to-role correspondence instead.
 *
 * No other role is withheld: every remaining role is consumed, or is contracted
 * to be consumed, by `base.css`, `components.css`, `sections.css`,
 * `responsive.css`, or `scripts/landing.js` under `design-system/COMPONENTS.md`,
 * `RESPONSIVE.md` and `MOTION.md`. Task 06 leaves one of the 147 —
 * `--state-disabled-text` — declared but no longer consumed at runtime; the
 * alias block at the foot of this file records why, and the role keeps its
 * accepted name and value so the Task 07 parity trace is unaffected.
 *
 * ADDED BY TASK 06 — 2 aliases, `--state-disabled-label` and
 * `--state-visited-on-ink`. Each is a reference to an accepted role, not a
 * value: this file still originates nothing.
 *
 * ---------------------------------------------------------------------------
 * OWNERSHIP
 * ---------------------------------------------------------------------------
 * 260802 Task 02 owns bilingual local font faces, package unicode ranges, and
 * the sole `:lang(vi)` token-value override. Task 03 local-font provenance is
 * preserved as history. Tasks 04–05 consume it without editing it. Task 06 may
 * add state/accessibility aliases. Any added role must first exist in
 * the accepted `design-system/` package — this file may never originate a
 * value.
 *
 * Responsive steps are exposed as explicit `*-tablet` / `*-mobile` roles and
 * this file holds no media queries, exactly as the accepted package does;
 * `responsive.css` performs the switch.
 * ========================================================================= */

/* Task 01 v4 correction — local, pinned design-system copies. Package
 * unicode-range declarations below are eligibility metadata, never glyph
 * capability evidence; tools/verify-font-routes.mjs checks every production
 * NFC scalar against the exact WOFF2 CMAP and Chromium PostScript identity.
 * The fallback stacks in the
 * family tokens below preserve the canonical metrics until each face arrives;
 * `font-display: swap` keeps text available and `font-synthesis: none` makes a
 * missing local byte observable instead of silently manufacturing a weight or
 * style.  These URLs are relative to site/styles/, so they stay inside the
 * publish root and cannot become a CDN fallback. */
