/*
 * Brand color alias block — SINGLE definition site for the whole site.
 * DraftWriter's page CSS (src/draftwriter/css/style.css) intentionally does
 * NOT redefine these; it inherits them from here because the global
 * stylesheet is loaded first (see partials/head.njk). This removes the
 * cross-file duplicate :root token definitions (requirement 3.5).
 *
 * The brand hex values below (#0181E3, #01477D, #FFBF00, #FF4900, #2c3e50,
 * #ecf0f1, #f8f9fa, #e0e0e0) have NO exact equivalent in the canonical
 * design-system tokens (src/css/tokens.css). Reconciling these brand values
 * to the DS semantic.primary scale is owned by the downstream
 * `consistency-refinement` spec — DS tokens.css is immutable here. They are
 * therefore kept as literals so the rendered colors stay identical (no visual
 * change). Only values with an EXACT canonical match are referenced via
 * var(--color-...) below.
 */

  /* --primary-blue / --primary-dark now reference the canonical DS semantic
   * primary scale. Via the consistency-refinement DS swap (task 1.1),
   * --color-semantic-primary-600-light = #0181E3 and -800-light = #01477D,
   * so these resolve to the EXACT same brand hex as before (zero visual change). */

/*
 * Compat alias layer (consistency-refinement task 2.1, design Component C2).
 *
 * These custom properties used to live in the legacy `css/design-tokens.css`,
 * which is no longer loaded by any page. The migrated DraftWriter
 * (src/draftwriter/css/style.css) and DraftCamera (src/DraftCamera/css/style.css)
 * stylesheets — plus a few rules in this file — still reference them. Because
 * this global stylesheet is loaded FIRST (tokens.css -> style.css -> extraStyles,
 * see partials/head.njk), defining them once here makes every var() resolve
 * for all downstream product CSS, eliminating the dangling references that were
 * falling back to CSS initial values in dist/ (broken typography / spacing /
 * shadows / tap-area).
 *
 * VALUE SOURCE: every value below is the ORIGINAL literal from the legacy
 * `css/design-tokens.css` (the single source of truth). No approximation — the
 * goal is zero visual change. A canonical DS token is referenced via var()
 * ONLY where its value is byte-identical to the original (font weights below).
 * `css/design-tokens.css` itself is NOT revived into src/ (Req 2.3); it is a
 * read-only value source. Reconciling these to the DS scale is future work for
 * the consistency-refinement spec.
