 * @description Styles for the AI Help Prompt page — warm white aesthetic,
 *   DM Sans body text, JetBrains Mono for the prompt code block.
 * @version-history
 *   v3.1.0 -- 2026-09-13 -- Compose the existing ink top rule from poster.css.
 *   v3.0.1 — 2026-08-29 — The prompt block reads var(--font-mono) instead of naming five monospace families.
 *   v3.0.0 — 2026-08-29 — The showroom face (design canvas "AIMEAT Index Pages"): no card, the title in
 *       the display face with the coral offset, the two tabs on a 3px rule with the open one on the
 *       sun, numbered steps with coral numerals, the questions as ink-framed boxes with a solid
 *       shadow, and the sun slab plus a door under "still stuck".
 *   v1.0.0 — 2026-03-23 — Initial implementation
 *   v1.1.0 — 2026-06-02 — Copied-state selector .hlp-copied → .copied (CopyButton component migration)
 *   v2.0.0 — 2026-07-28 — Two-tab shell (.hlp-tabs/.hlp-tab), human help (.hlp-steps/-questions/
 *     -answer/-stuck) and the rendered-markdown prompt box (.hlp-prompt-rendered). The page used
 *     to print the prompt's markdown source at a human who clicked "Help".
 *   v2.1.0 — 2026-08-08 — .hlp-copy-btn deleted — it reimplemented .btn-primary exactly (same gradient, same hover
 *       lift) and .hlp-copy-btn.copied reimplemented .btn-primary.success. Only the wider CTA
 *       footprint survives, as a container rule.
