/*
  Shared stylesheet of the public legal pages (privacy.html, privacy-en.html, support.html).

  Audience: a store reviewer, or someone deciding whether to install - both want to confirm in half a minute what
  happens to their photo. So the page opens with the path one photo takes (device -> server -> result -> gone) and
  everything after it is a quiet, left-aligned reading column.
  Colours are the app tokens from constants/colors.ts and nothing else. The verdict colours (real / uncertain / ai)
  are deliberately absent: nothing on these pages is a verdict. "Kept" vs "not kept" is said in words and in the
  line style of the path (solid = travels, dashed = discarded), not in colour.
  No web fonts, no scripts, no third-party requests: a privacy page should not call anyone.
