/* ==========================================================================
   DELTA TANGO SHOWCASE LAYER (showcase.css)
   Shared by /ai, /ai/blueprint and /tech. Loaded after the page stylesheets.

   1. Theme tokens: dark (Night Ops, default) and light (Day Ops), resolved
      from the visitor's saved choice or their operating system setting.
   2. Elevated presentation: aurora backdrop, display typography, glass
      surfaces with pointer spotlight, pill controls, refined tables and forms.

   Copy is untouched; this file only changes presentation.
   Tokens only, no hardcoded utility colours. Zero emdashes. Australian English.
   ========================================================================== */

/* --------------------------------------------------------------------------
   1. THEME TOKENS
   Dark values match the original literals so Night Ops renders as before.
