/* Reading Tabs sidebar block.
 *
 * Colour: the block follows the active theme's primary colour on its own.
 *   1. A theme may pin the colour with --rt-accent (and optionally --rt-accent-dark, --rt-tint, --rt-line) on :root.
 *   2. Otherwise a small script in the block reads the theme's link colour and sets --rt-accent on the block.
 *   3. Tints, borders and hover shades are always derived from that one accent (color-mix), so nothing is hard-coded.
 * The teal below is only the last-resort default (no theme variable, no script, or a browser without color-mix).
