/* =========================================================
   Mia Ideas — app styles
   Brand palette from the Mia Bazo guidelines, same tokens as Mia Brain's public.css:
     #c46412  primary deep (burnt orange)
     #dd7904  primary (mid orange) ← anchor
     #f7931e  primary bright
     #333333  ink (charcoal)
     #f5bb3b  amber (supporting)
     #118ed4  blue, #63ad71 green, #c13936 red, #6c58b3 purple (status accents only)

   Unlike Mia Brain, which brands only its public pages and leaves the signed-in app on
   stock bootstrap-dark, the whole of Mia Ideas uses the brand shell — signed in or out.
