/*
  Amacoco public site -- shared stylesheet.
  Mobile-first. No framework, no build step -- plain CSS so anyone can
  open this file directly and change colors/spacing without tooling.
  Edit CSS custom properties below to retheme the whole site at once.

  Theme: white-based, single-column beauty site. No black background,
  no dashboard-style card grids -- long-scroll sections with generous
  whitespace, alternating very light section tints, and large photo
  placeholders.
