/* ==========================================================================
   فر دیزاین — base.css: tokens + shared components (docs/06).
   Provenance: component rules (.btn, .seg, .menu, fields, toasts, tooltip, dialog, tabs, kbd)
   are extracted from the legacy plan-editor.html; the paper/ink palette and panel patterns come
   from legacy app/house-3d.html. Since IN-039 the palette is navy ink + drafting blue, a rose CTA and pastel tones.
   Legacy variable names (--text, --border, --accent-2 …) stay as aliases so the ported editor works.
