/*
 * brief/blocks.css - repeated blocks in brief mode: header, claim chips,
 * cards, the fleet table, CTA, footer, mode indicator.
 * Dependencies: brief/tokens.css, brief/layout.css.
 * Invariants: scoped under [data-mode="brief"]; colours come from tokens.
 *             Tints rotate by :nth-child so a grid reads as a set without
 *             per-card classes in the HTML.
 * Non-goals: no page-level structure; no mode-switching logic.
