/*
  Palácio Itaigara — institutional site, served on the root domain by the
  `landing` container (see docker-compose.yml). Plain HTML/CSS, no build
  step: this directory is bind-mounted straight into nginx.

  Colors match the resident app's own palette (frontend/src/index.css,
  :root[data-portal='resident']) so the public site and the portal a
  resident eventually logs into read as the same brand.

  Sizing is mobile-first and deliberately unchanged from the original build
  below 48rem (768px) — everything under "Desktop enhancements" at the
  bottom of this file only takes effect at or above that width: bigger type,
  a wider .wrap, and a hero that fills the first screen. A phone or a small
  tablet never sees any of it.
