/* TAI Labs GovTech site.
 *
 * Deliberately the same register as the Open DSA dashboard it fronts: a
 * statistical agency, not a campaign. The pitch is that our numbers survive
 * hostile review, so a page that reads as persuasion argues against itself.
 * No hero imagery, no gradients, no animated counters, no logo wall.
 *
 * Tokens mirror web/src/styles/tokens.css. This is the only file here where a
 * raw colour value may appear.
