/* PRESET-IO — Phase 6 presets-browser modal + topbar Presets button +
   <main> drag-drop cue + body fallback toast for the no-builder state.

   The presets browser follows the Phase-4 ontology browser conventions: native
   <dialog>, dark-mode [data-theme="dark"] overrides, responsive collapse at
   max-width 720px, delegated click handling on the dialog itself (no per-
   button listener wiring). */
