/* NEETAce design system - one look for every page.
 *
 * Loaded last on every page (see scripts/apply-theme.js). The theme comes from
 * the student's own choice in the app (localStorage na_theme), applied before
 * paint by /lib/theme-boot.js, so moving between pages never switches look.
 *
 * Tokens use html:root[data-theme=...] so they win over the older per-page
 * :root palettes without editing every page. Older variable names used across
 * pages (--card, --panel, --ink, --line, --brand ...) are aliased to the same
 * tokens.
