/* The seam band and the rail section.
 *
 * SCOPED TO .seam AND .rail. A page stylesheet with bare element rules restyles
 * the nav and the footer — learned the hard way on the track-bias page.
 *
 * @keyframes ARE LEFT ALONE: they are not selectors, prefixing them is
 * meaningless, and scoping them destroys the animation. Names carry an rl-
 * prefix so they cannot collide.
 *
 * Tokens come from site.css. The six jackets are the real GB trap colours,
 * dimmed to sit on a dark panel.
 */

/* --mint IS DEFINED HERE, not in site.css.
 *
 * The bright green that reads on a dark panel — the site's --green is tuned for
 * white paper and disappears against --green-deep. It is scoped to the blocks
 * that use it rather than added to :root, because it is a dark-surface colour
 * and putting it in the global palette invites it onto light pages where it
 * has no contrast.
 *
 * It was missing entirely at first: I stripped :root from this sheet on the
 * grounds that tokens belong to site.css, and mint was the one token that was
 * never there. background:var(--mint) resolved to nothing, so the active tab
 * and the solid button rendered as near-black text on no background at all.
