/* modal.css — Single-run detail overlay.
 *
 * Composition:
 *   .modal-overlay  → fixed backdrop, fades in when .open
 *   .modal-shell    → centered card (max-w 760px, max-h 88vh, scrollable)
 *     ↳ header (title + subtitle + close)
 *     ↳ tab bar (Details / Visualize / Implementation)
 *     ↳ body (one .modal-panel per tab, only .active is shown)
 *     ↳ footer (submission id + reproduce link)
 *
 * Suite accent on the shell uses [data-suite="A"..G"] → --suite-color
 * (same scheme as rankings.css), so the modal picks up the same hue as
 * the suite the run belongs to.
