/* ===========================================================================
 * Portal components — the "Assurance Dossier" visual language.
 * ===========================================================================
 * Every value here is a token from `src/design/tokens.generated.css`, which is
 * itself generated from `design/tokens.json`. No literal colours, spacing or
 * durations appear below: `tests/unit/tokens-sync.test.ts` fails the build if a
 * raw hex value does, and the token file is the single source of truth.
 *
 * The three devices that make this not look like every other trust portal
 * (see the design brief §3.1):
 *
 *   1. Layered substrate — depth comes from *material change and rules*, never
 *      from drop shadows. Only the overlay level casts a shadow.
 *   2. The ledger rail — a monospace left gutter carrying item number, date and
 *      status, which makes a document list read as a register rather than a
 *      card grid.
 *   3. The evidence keyline — a verdigris rule present only on asserted
 *      evidence, absent from chrome, so a visitor learns in seconds that a
 *      keyline means "there is a file behind this".
 * =========================================================================== */
