/* ============================================================
   DOCKBOX — MERIDIAN theme layer (v3 "Floating Shell")
   Modern, sleek, premium. Loaded LAST in the cascade: redefines
   both token systems (style.css + tokens.css) and restyles
   existing selectors only. No markup/ID changes — app.js untouched.

   The shell is rebuilt as panels floating over a tinted gradient
   field: detached frosted sidebar, floating topbar, glass content
   panel, pill composer, gradient accent.

   Light = "Daylight"  (default) — slate-blue wash, glass, cobalt→violet
   Dark  = "Midnight"  — deep blue-black, glow blooms, periwinkle→violet

   Type:  Bricolage Grotesque (display) / Instrument Sans (body)
          Geist Mono (code, meta, eyebrows)
   ============================================================ */
