/* Podcast player, one component family for the article pages and
 * /insights/podcast/ (driven by assets/podcast/podcast.js, markup from
 * tools/build-podcast.py). Colours are the handoff tokens, so the file works
 * on any page that loads it.
 *
 * Shared parts, the same everywhere:
 *   .i-play / .i-pause   the play and pause symbols, one size
 *   .pod-btn             primary pill: white circle with the symbol + label
 *   .pod-btn2            secondary pill (All episodes, Get new episodes)
 *   .pod-plat, .ep-plat  round icon links to Apple Podcasts and Spotify
 *   .pod-round           round play / pause (.is-lg larger, .is-soft grey)
 *   .pod-wave            waveform slider with a playhead
 *   .pod-time, .pod-rate time and speed
 * Compact variants: the byline player in the article and the mini player.
 * Expanded variants: the episode card (#episode) and the latest episode on
 * the podcast page. Panels: 1px #E6E9EE border, radius 24 (large) or 16 (small). */
