/* ── Easter-egg tabs ─────────────────────────────────────────────────────────
   A panel carrying `data-tab-secret` gets `is-secret` on its strip button
   (js/figure-tabs.js), and the button collapses to a sliver until it is
   hovered, focused or open. The label is still in the DOM the whole time —
   only its width is taken away — so the keyboard walk and a screen reader
   still find it; `color: transparent` rather than `display: none` is what
   keeps that true.

   The sliver is not invisible: it keeps a muted piece of the strip's own rule,
   so what shows is two short dashes past the last real tab. Something to
   notice, not something to read. */
