   GREENTECH REAL ESTATE — Apartment Selector (Noir & Gold)
   Full-screen overlay: tower ELEVATION (left) · top-down FLOOR PLAN (centre) ·
   apartment DETAIL (right slide-in). All styles scoped under `.gt-selector`.
   Reuses the global tokens from tokens-realestate.css (var(--gold) etc.).

   STATUS → COLOUR (single source of truth, driven by [data-status]):
     disponibil → gold glow      (var(--gold), filled + soft bloom)
     rezervat   → muted bronze    (var(--gold-deep) at low alpha, dim)
     vandut     → faint / dark    (onyx fill, low opacity, no interaction shine)
     la-cerere  → bone outline     (transparent fill, bone stroke)
