/*
 * Codeliance Design System — canonical design tokens.
 * ============================================================================
 * Single source of truth for every color, type size, radius, spacing step,
 * shadow, and motion value in the app. Every screen reads its values from a
 * named token here — never a raw hex or pixel number.
 *
 * COD-230 (design token system). Values are lifted verbatim from Einat's
 * "Codeliance — Token Reference" handoff (the design source of truth); this
 * file IS the codebase implementation of that spec.
 *
 * NOT WIRED UP YET — nothing loads this file. Wiring is COD-231 (Build the
 * core component library), Step 0:
 *   1. point core/templates/base.html at this file;
 *   2. migrate the scan funnel off the legacy core/static/css/design-tokens.css
 *      onto these tokens — INCLUDING swapping the funnel's font <link> from
 *      IBM Plex Mono to Roboto Mono, else funnel mono text (10+ var(--mono)
 *      usages) falls back to a system font once --mono changes;
 *   3. delete the legacy design-tokens.css so both surfaces share one system.
 * Committed as a SEPARATE file (not an in-place overwrite of the funnel's
 * design-tokens.css) precisely so this commit can't regress the live funnel
 * before that reviewed migration.
 *
 * ── Fonts ──────────────────────────────────────────────────────────────────
 * This file only DECLARES the families (--sans / --mono). The faces are now
 * SELF-HOSTED (COD-233) in core/static/css/fonts.css: DM Sans + Roboto Mono as
 * @font-face served from core/static/fonts/ (latin + latin-ext woff2, variable
 * fonts with a font-weight range). Self-hosting was preferred over a Google
 * Fonts <link> because the app runs a nonce-based CSP — 'self' covers the woff2
 * with no font-src/style-src exception and no third-party dependency. Base
 * template loads fonts.css before this file. (The funnel still uses a Google
 * Fonts <link>; migrating it onto fonts.css is a separate follow-up.)
 *
 * ── Reconciliation notes (for the move into hub, COD-231) ───────────────────
 *  • Will supersede the legacy funnel design-tokens.css (created for the free
 *    scan, COD-235) once COD-231 migrates the funnel onto this file. Until then
 *    both coexist and the funnel is UNAFFECTED by this commit.
 *  • --text-muted / --text-sub are DARKER here than the legacy funnel values
 *    (#5f6377 vs #8a8fa8, #6a6e85 vs #b0b5c8) — intended contrast/accessibility
 *    improvement from the reference; the funnel picks this up when migrated
 *    (COD-231).
 *  • DROPPED from the old funnel file (all had zero var() usages in-repo):
 *    --blue-mid (a mislabeled teal — the reference resolves it into --teal),
 *    --navy, and --red/--red-bg/--red-border.
 *  • Negative / error color: the Token Reference defined no token; a muted rose
 *    was added here PROVISIONALLY pending Einat's sign-off on name, hue, and the
 *    variant shades. RESOLVED 2026-07-22 — Einat's COD-231 additions spec
 *    (design/new-design/codeliance-additions.css) sets the approved values: a
 *    true critical/destructive red (--red #b91c1c) plus --red-dark for the
 *    destructive-button hover, and --border-strong for empty container controls
 *    (select, textarea). The name --red stayed (the spec uses it); the earlier
 *    muted rose (#b8636e) is superseded.
 *  • --gray-soft is the ONLY funnel-only token still referenced (funnel
 *    report.css table backgrounds) — kept below as legacy; migrate in COD-231.
 *  • Type scale is 7 steps, not the 6 named in the COD-230 ticket text: the
 *    reference added --fs-read (15px) for prose/detail body after the ticket
 *    was written. The reference is authoritative.
