/* Shared "Khối màu" primitives for the smaller redesigned pages.
 *
 * The first ten pages each got their own stylesheet, which was right while every
 * page needed a different layout. These four — documents, technical-basics,
 * assessment-rankings, thank-you — are the same shape: a coloured hero, a ruled
 * list or grid, a closing strip. Eight more near-identical files would be eight
 * more places to fix the same defensive rule, so they share one set of
 * primitives under .fp- and add only what is genuinely their own.
 *
 * House rules: radius 0, no shadow, no gradient, no translucency.
