/* ===================================================================
   Keyword Rank Checker (/keyword-rank-checker)

   Scoped under .krc. Same structure as the Backlink Maker (.bm): reads the
   site-wide --az-* tokens and adds only an accent, the rank groups and
   motion.

   Accent: the A-Z palette colour for the letter K (az-color-palette.js,
   primaryForLetter("K") = #a45ae2). --krc-accent-strong is the same hue
   darkened for text on white.

   Motion is decoration only - every rank group is also carried by text -
   and prefers-reduced-motion switches it off at the bottom.
