/*
  BintaCura — stylesheet for the static, crawlable public pages.

  These pages are plain HTML served as files by nginx, alongside the Flutter
  SPA. They exist because the application renders into a WebGL canvas: its
  visible text never reaches the DOM, so a crawler that renders the app still
  extracts no content (measured: 30 characters of DOM text on the homepage,
  all of it Flutter's hidden "typography measurement" node).

  Kept dependency-free and small on purpose: no webfont fetch, no framework,
  no build step. Anything that needs the application is reached through a
  link into the SPA (a hash URL), never reimplemented here.
