   Vandyman Build Studio — SHARED STUDIO UI (studios.css)
   Paid design-studio system. Loaded AFTER studio.css, so it
   REUSES the brand variables defined there and never redefines
   them: --ink/--ink-2/--ink-3, --cyan, --blue, --sand,
   --text-d/--text-d-mut, --grad, --line-d, --radius, --f-display,
   --f-mono, --f-body, plus button classes .btn .btn--primary
   .btn--brass .btn--ghost .btn--quiet.

   Goal: a genuinely premium dark-blueprint studio feel (CAD /
   spec sheet), NOT a generic calculator. Soft glows, mono labels,
   measurement-tick accents, generous spacing, fully responsive.
