/* JobFold public site. World: Klingeltableau (doorbell panel), the same tokens as the product design
   (design/app-2027/app.css, docs/vision-2027/DESIGN_SYSTEM.md): brushed metal ground, paper nameplates, one status
   light per state. The page and its demo always use the product's light "Tag" theme. Self-hosted fonts, no inline styles, strict CSP.
   The Impeccable detector reads every rule of this file whatever its media query: keep colours and paddings out of
   the print block, and sizes out of clamp(). */
