/* Design "papier" – Papier & Marker (docs/DESIGN.md §1).
   Bullet journal: paper white with a dot grid, ballpoint blue as the pen, highlighter strokes
   for the four fields and for what is urgent, notes with a strip of tape and a tiny tilt.
   Dark: "Tafel" – deep green board (= theme-color of core/design.py), chalk-white writing,
   pastel chalk highlights.
   Headings: Caveat 700 (handwritten, set large), body stays Atkinson Hyperlegible.
   Token contract: see the head of pop.css. Contrast: core/tests/test_design.py (WCAG AA).

   Besides the shared tokens this file uses a few private helpers (prefix --pp-, defined in the
   token blocks so light and dark stay in one place):
     --pp-pen       colour of handwritten headings (ballpoint blue / chalk)
     --pp-chalk     the soft edge of chalk writing (dark only, a text-shadow)
     --pp-note      lighter paper on a yellow sticky note (what sits on the highlighter)
     --pp-tape      the translucent tape strip on notes
     --pp-hl-*      highlighter strokes (yellow = --marker, pink, blue, green) and --pp-hl-ink,
                    the text colour on them
     --pp-smudge    chalk dust on the board (dark only, an image layer)
   Static motion only: the tilt of the notes is a fixed angle; straightening on hover/touch is a
   transition, which hausbuch.css switches off for prefers-reduced-motion.
   Everything below the token blocks is scoped to [data-design="papier"], so the live preview
   cards of the other designs (Konto, "Mehr") are never touched. */
