// =============================================================
// Video Editor — loading skeleton
// Mirrors the 3-zone shell (top bar · stats · rail · panel · stage ·
// config) with shimmer placeholders. Self-contained: does NOT use
// `assets/src/css/_common.scss`. Neutrals are derived from
// `currentColor` so the skeleton follows the admin colour scheme; the
// "Save" placeholder picks up the WordPress component accent.
