/* Per-category panel accent — TOGGLE FEATURE (user 2026-05-25 v15).
   Adds a subtle blue/green/yellow/orange tint to the main panel(s)
   of every tool, based on which category the tool belongs to
   (Learn / Practice / Play / Tools). The accent is a border-color
   shift toward the category hue + a faint inner glow tinted the
   same colour.

   Loaded + activated by js/core/nav.js which:
     1. injects this stylesheet on every page that has a nav
     2. adds `body.cat-learn|practice|play|tools` based on the
        current page's category in NAV[]

   TO REVERT THE WHOLE FEATURE: see js/core/nav.js block tagged
   `CATEGORY ACCENT FEATURE — delete this whole block to revert`,
   delete that whole block, delete this file, and revert the four
   --cat token values in index.html lines 335-338. One `git revert`
   on the commit that added this file rolls back everything in one
   step. */

/* Panel selectors per tool. User 2026-05-25 v15-tweak: jazz-standards,
   harmony-trainer, tuner and metronome get NO accent — they're explicitly
   excluded by removing their dial/stage selectors from the list.
   .bt-mixer (not .bt-panel) is BT's actual main panel. */
/* OLD accent style (border tint + inner glow) — REMOVED 2026-05-25
   v17 per user: "haal bij elk van de gekleurde panel randen de glow
   weg. de panel rand moet weer gewoon grijs zoals het was". New
   accent style sits in panel-layout.css for CoF only as a test. */
