/*
  Placement Gurus CMS. One small stylesheet, system fonts, no web fonts and no CDN.

  Palette from DESIGN.md: page #ECE8E4, card #FDFCFC, text #2E1F1F, muted #846262, accent
  #7E1A1C, secondary #3B6866, border #E5DEDC. Two additions exist only for readability and
  are the same hues, darker: muted text on the page background (the exact muted colour is
  4.4:1 there, 5.2:1 on a card) and the border of a form control (the soft border is 1.1:1,
  a control's edge needs 3:1). tests/test_ui_pages.py checks every pairing below.

  The theme library pages load a theme's own stylesheet, which defines --background,
  --primary and so on. Nothing here uses those names (ours are --cms-*), so a theme can
  never restyle the CMS itself; only the .tp-* sample blocks read the theme's variables.
