/* hero.css — Bappa in one gold line, the names, and the marquee.
 *
 * Entrance (js/hero.js adds .is-in as the gate lifts, .is-drawing for the draw):
 *   the line art is uncovered bottom-up (lotus → crown) by a soft mask edge, then the
 *   name letters rise out of their line boxes one by one.
 * Afterwards a gold foil highlight rides the line art: .hero__foil is masked by the
 * art itself, and its spot child only ever moves by transform (compositor-only).
