/*
 * Film set theme — tokens and shared components for every signed-in portal page.
 *
 * The world you signed in to continues: a dimmed, blurred still of the film set
 * behind frosted glass. Linked AFTER styles.css, which keeps the sign-in screen's
 * pinned :root and background untouched. Portal CSP is style-src 'self': no <style>,
 * no style= (SVG included). Dynamic values go through CSSOM from same-origin JS
 * (assets/illustrations.js). Motion lives in assets/motion.css.
 *
 * Vocabulary other pages reuse (do not fork):
 *   body.fs-backdrop          the fixed, blurred film-set still behind a page
 *   .fs-glass / .fs-glass-strong    frosted card surface / dense-data surface
 *   .fs-tile + --good|--warn|--danger|--info   state tile (neutral without a modifier)
 *   .fs-kicker .fs-value .fs-unit .fs-sub .fs-tile-link   tile anatomy
 *   .fs-banner + tone modifiers, .fs-banner-copy .fs-banner-title   one-line state banner
 *   .fs-grace                 the deletion grace banner account-status.js puts inside every
 *                             account page (a .fs-banner with a counting-down ring)
 *   .fs-pill + tone modifiers  plain-word status (Active, Invited, Paid, Due …)
 *   .fs-button, .fs-button--primary   quiet glass button / the single red action
 *   .fs-empty                 empty state: one illustration, one sentence, one action
 *   .fs-toast                 bottom-centre glass notice (Undo lives here)
 *   .fs-art, .fs-art--corner  illustration host (illustrations.js builds the SVG)
 *   .fs-sr                    visually hidden, still read aloud
 * A tone modifier sets --fs-tone-label / --fs-tone-sub / --fs-tone-action / --fs-tone-art,
 * which every child (kicker, links, ring, meter …) reads.
