/* Visual language borrowed from the Browser Profiles design system: semantic
 * tokens, thin borders, moderate radii, compact table density, indigo accent.
 * Only the language — no components or business code are copied.
 *
 * Deviation, on purpose: Vela Sans is not shipped here. Bundling the font would
 * mean adding font-src to the CSP, and the security headers are out of scope
 * for this change, so the system stack is used with the same size/weight scale.
