/* =====================================================================
 * === Marked mistakes (added 2026-11-06) ===
 * The marked mistake card from the UI/UX audit, section D1. Class names
 * are fixed by that spec: .mark-card and its parts, .script, .working,
 * .mark, .pen-ring, .pen-note, .mark-stamp, .frac, .sqrt; plus the compact
 * .mark-card--mini (one panel, for heroes and in place of pictures).
 * site.js adds .is-marked at about 45% visibility. Without JS the final
 * marked state shows, because the hidden state is scoped to .js.
 * Ruled rhythm: one working line = one ruled line = --mk-band, which is
 * 2.4 x the working size (the same as --line-gap at that size).
