/* ─────────────────────────────────────────────────────────────────
 * css/board-notes.css
 *
 * Styles for the per-board collaborator notes feature (PILOT-READY,
 * 2026-05-27). Owned by js/builder/board-notes.js. Loads AFTER
 * builder.css so brand tokens (--ink, --ink-muted, etc.) are in scope.
 *
 * Surfaces:
 *   • .board-notes-pill        — the 📝 chip in the MY BOARDS row
 *   • .board-notes-backdrop    — modal backdrop
 *   • .board-notes-panel       — slide-in panel (right side on wide,
 *                                 full-screen on mobile)
 *   • .bn-*                    — sub-elements inside the panel
 *
 * Role badge colors:
 *   parent  → blue
 *   slp     → green
 *   teacher → amber
 *   other   → gray
