/*
 * jmm/youtube-playlist. Every rule is scoped to .jmm-ytpl.
 *
 * A dark box, like the old Nyttiflempan column: #222, white text, compact rows with
 * 16:9 thumbnails 120 px wide. The block is its own container, so it lays itself out by
 * its own width and not the window's: stacked in a narrow column, the list beside the
 * player when there is room. Theme.json presets are used where they exist (the font
 * sizes, the accent colour for focus and for the playing item), with the dark look as
 * the fallback.
