/* ═══════════════════════════════════════════════════════════════════════════
   Unified Workflow Framework — layout + shared components
   ─────────────────────────────────────────────────────────────────────────
   DESIGN SYSTEM (Rony Scarfati):
   Single shared stylesheet for every workflow.  No per-workflow CSS.
   New workflows are composed entirely from JSON — this file + the
   partials (_wf_image_drop, _wf_radio_group, etc.) handle all rendering.
   ═══════════════════════════════════════════════════════════════════════════ */

/* ══════════════════════════════════════════════════════════════════════════
   DESIGN RULES (Rony Scarfati):
   - Every component type has ONE fixed size — content adapts inside.
   - Drop zone = drop zone, gallery = gallery, button = button.
   - Never vary dimensions based on content count or workflow type.
   - Single column flow — same on desktop and mobile.
