/*
 * Living Panels reader — ported from the site's episode-view component so the
 * episodes match the product reader. SCSS tokens are resolved to literals:
 *
 *   #131313 black-base   #fafafa white-base   #ffffff white
 *   #c7ffc7 green        rgba(199,255,199,.6) green-60
 *   #80ff00 green-accent rgba(255,255,255,.15) white-15
 *
 * Panels are a single vertical column. Each <section class="panel"> is a fixed
 * aspect-ratio box holding, stacked: the poster <img>, the looping <video>
 * (hidden until it actually plays, hence `.live`), any bubble/SFX overlays
 * (revealed by `.pop`), and the caption.
 *
 * State classes driven by the reader:
 *   .in       panel is meaningfully on screen
 *   .live     its video is decoding and playing — fade the video over the poster
 *   .pop      reveal the bubble/SFX overlays
 *   .speaking a voice line is playing — show the caption
 *   body.dark a `dark` panel is on screen — fade the whole page to black
 *   body.nosubs  manifest.subs === false
 */

/*
 * ---------- Global reset (from the marketing app's styles.scss) ----------
 *
 * WordPress port: scoped to `body.living-panels` (the class this template adds
 * via body_class), so the reset cannot reach anything WordPress puts outside
 * the reader.
 *
 * The scope sits inside `:where()` on purpose. A reset has to stay the weakest
 * rule on the page — plain `body.living-panels *` scores higher than the very
 * rules it is resetting, so `margin: 0` here would beat `.images-scroll`'s
 * `margin: auto` and knock the panel column out of the centre. `:where()`
 * contributes no specificity, keeping this exactly as weak as the bare `*` it
 * replaces.
