/* =============================================================
   29th Street Capital — modern product-UI redesign
   Structure & UI language follow the reference app aesthetic:
   soft light canvas, white elevated cards, pill badges, centered
   section headers, two-tone headings, small icon tiles.
   Brand colours and fonts remain 29SC's own:
   navy #0F426B · terracotta #D5835E · Lora + Barlow.
