/* ------------------------------------------------------------------
   /changelog — daily timeline of shipped changes, a month per page

   Self-contained, `cl-` prefixed. Brand variables come from styles.css,
   loaded globally by root.tsx; the hero classes come from
   feature-page.css, which the route loads alongside this file.

   The card is the guides-index accent-stripe card, with one deliberate
   difference: here the stripe colour encodes the CHANGE TYPE (new /
   improved / fixed / performance), matching the pill on the card, so a
   scanning reader can pick out "the new stuff" by colour alone.
   ------------------------------------------------------------------ */

/* ---------- change-type colours ----------
   One custom property per card, set by data-type, consumed by both the
   stripe and the pill. New owns the brand green, Improved the purple,
   Performance the brand teal; Fixed stays deliberately neutral grey —
   fixes are housekeeping, not headlines. Yellow is reserved for the
   "since your last visit" marker so that signal is unmistakable. */
