/* --- MODAL SIZE VARIANTS (shared — add ONE class instead of being hardcoded) ---
   The big per-app ID list above (#previewModal, .doc-preview-modal, #docViewer …)
   gives those modals a fullscreen size. New code should instead put a size class on
   .modal-content so any modal — in any app — opts in without editing this file:
     .modal-fullscreen  → near-edge-to-edge (the "1:1"-style big iframe / doc viewer)
     .modal-md          → default ~600px floating bubble (no class needed)
