/*
 * BDeBooks shared foundation, final design f3 (Claude Design package 2026-09-29, installed
 * exactly: bdebooks/design/DESIGN-F3-INSTALL-2026-09-29.md). The values are the design's own
 * (0-2 Design spec, BDe Header, BDe Footer, 9-1/9-2 sources and bde-site.js), copied, not
 * approximated. Loaded on every public page after every older stylesheet, so it wins by order.
 *
 * What lives here (Stage 1, foundation): design tokens, base type, the shared chrome (header,
 * menu drawer, language menu and sheet, phone tab bar, footer), the book card and its house
 * cover, the author avatar, and reusable controls: buttons, fields, chips, segmented switches,
 * tags, sheets and dialogs, status panels, empty and error states, section heads, shelves and
 * grids. Page families (home, lists, book, reader, pages, account) build on these classes in
 * their own family-*.css; nothing page-specific belongs here.
 *
 * Every chrome and component class starts with f2- so it can never collide with a v3 rule.
 * The legacy variables the older page CSS reads (--ink, --accent-ink, --blue ...) are pointed
 * at the f2 palette below, so pages not yet moved already sit in the new colours.
 *
 * Contrast (WCAG 2.2 AA, measured): coral #C9401F 4.96:1 on white, 4.69:1 on page, 4.56:1 on
 * #FFF3EE; coral-dark on coral-tint 5.61:1; muted #6E605A 5.70:1 on page, 6.03:1 on white;
 * night-band text #C4BEE6 8.15:1 on #2A2350. Field borders use --f2-field-edge #9B8B84 (3:1 on
 * every surface, owner 2026-09-30); cards and buttons keep the design's #EBD6CC.
 * The accent #E4532F (focus ring, play) is never behind or under small text.
