/* ============================================================
 * LESKOV — unified media player styles (audio + video)
 *
 * Single source of truth for every player surface: header premium
 * player, promo bar, inline track cards, video tiles, etc. They all
 * share the same primitive — `.leskov-player` — with variants.
 *
 * Variants:
 *   .leskov-player           — root, required
 *     .leskov-player--compact   small inline card (track rows)
 *     .leskov-player--featured  large hero / header / premium
 *     .leskov-player--video     video surface (bio / gallery / story)
 *     .leskov-player--bottom    pinned to viewport bottom (used in R8)
 *   .leskov-player__cover    — cover art container
 *   .leskov-player__media    — the <audio>/<video> element itself
 *   .leskov-player__panel    — control bar / overlay
 *   .leskov-player__title    — track / video title
 *   .leskov-player__artist   — subtitle / artist / handle
 *   .leskov-player__time     — current / duration labels
 *   .leskov-player__seek     — progress bar
 *   .leskov-player__volume   — volume slider
 *   .leskov-player__controls — buttons cluster (play/pause/prev/next)
 *   .leskov-player__btn      — generic round control button
 *   .leskov-player__btn--play  large central play/pause
 *
 * The component is fully driven by data-* attributes so the JS layer
 * (LeskovPlayer in scripts/player.js) can stay in charge of state
 * without coupling to CSS class names beyond the root.

/* ============================================================
 * DOCK — pinned bottom-bar player
 *
 * Rendered on every page; lives in <div class="leskov-dock"
 * data-dock>. Hidden by default, slides up when the user starts
 * playing something via the data-play-in-dock trigger or after a
 * page load that restored a previous session. The dock uses a
 * hidden LeskovPlayer instance under the hood so it can re-use the
 * existing persistence, seeking, and event machinery.
 *
 * The dock has two visual states:
 *   .leskov-dock                 — full bar (default once visible)
 *   .leskov-dock[data-collapsed] — compact, just the play button + cover
 *                                  (used on small screens / when the user
 *                                  explicitly collapses the bar)
