/**
 * gr_annotations.js  —  grantha.io inline Notes + Bookmarks + Feedback  (v3)
 * ══════════════════════════════════════════════════════════════════════
 *
 * CHANGES FROM v2
 * ────────────────
 * • "Comments" renamed to "Notes" throughout. Notes are user-local
 *   (localStorage only, not saved to wiki Talk pages).
 * • Comment icon replaced with notes.svg (same path convention).
 * • New "Feedback" button (flag icon) replaces the old comment FAB button.
 *   Shows a popup with:
 *     - Highlighted text (read-only)
 *     - Issue type: Wrong text / Reference issue / Spelling mistake / Other
 *     - Free-text area
 *     - Email field for user's address
 *   Submits via EmailJS / fetch to admin@anandamakaranda.com.
 *   NOT stored anywhere on the wiki. NOT shown in the panel.
 * • Notes panel tab uses notes.svg icon.
