/* ============================================================================
   Auraz Academy — development client
   ----------------------------------------------------------------------------
   Built on the Auraz shared foundation (ERP css/tokens.css): the formal palette
   is red and white, and black and red in dark mode. Never gold — an early
   landing draft used a gold accent and was corrected by the owner.

   Carried across verbatim so the Academy reads as the same product:
     · --az-red #C7312E, deep #A22323, soft #E2574E (accent TEXT on dark, for AA)
     · black surfaces #08090C / #101318 in dark, white in light
     · interactive corners = 6px, inputs = 6px, cards = 14px
     · one motion bezier, cubic-bezier(.32,.72,0,1), at functional speed
     · the shared top bar uses the active theme and stays stable across views

   The brand families (Cabinet Grotesk / Satoshi) are not installed here and
   this build fetches nothing, so the stack falls through to the brand's own
   declared fallbacks rather than substituting a different personality.
