   -----------------------------------------------------------------------
   Color system: brand colors are #00E8FC (teal), #E2A9F1 (purple),
   #FFDE59 (gold). Teal is the most saturated/attention-grabbing of the
   three, so it is used sparingly as a "signature" accent (logo, one
   hero moment). Purple is the lightest/softest, so it carries most of
   the repeated small UI accents (dots, borders, chips). Gold is kept
   for rare, transient highlights (hover states). This keeps the exact
   brand hues while avoiding a page that reads as uniformly loud.
