   LISEUSE v2 — tts-notes.css : compléments « lecture vocale + bloc-notes »
   ─────────────────────────────────────────────────────────────────────────
   Module : tts.js (dock [data-tts-dock]) + notes.js (panneau [data-panel-notes]).
   Contrat : n'utilise QUE les tokens :root de v2.css (var(--acc), --glass-*,
   --stroke, --r-*, --shadow-*, --display, --ui, --serif, --paper…). Le socle
   .tts-dock / .panel / .panel__tabs / .panel__tab est déjà stylé par v2.css ;
   ici on ne fait qu'AJOUTER (contenu interne du dock et du panneau).
