   Food Delivery App Development Services — the sections added
   2026-11-03 (definition, business-model table, how-to steps,
   Uber Eats build-like cards, tech stack pills, revenue models,
   cost table). The page's original sections keep their own
   styles; everything here is fd- prefixed so nothing collides.
   Palette from variable.css: brand red #ec2024, red tile #fdecec.
   common.css already gives every <section> 90px vertical padding.
