/*
  Holding page styles. Deliberately one plain stylesheet and ZERO JavaScript:
  this page has to survive unattended for weeks, so there is no build step to
  rot, no bundle to go stale, and the CSP can stay at default-src 'none'.

  Palette and fonts are lifted from src/index.css so the pause still looks like
  HYPD. Light values on :root, dark swapped under prefers-color-scheme - there
  is no theme toggle here because there is no script to remember one.
