/* Villa papers checker. One page, four states.
   COPIED FROM work/2026-09-26-jason-mvp/app.css @ 25c4d64: the design tokens, body, focus ring, select and file
   input look, buttons, status chip, scrolling table box and the reduced-motion rule. Changes: only those parts,
   the word "Papers" kept as the product name, no dark mode (the desk has none).
   NEW (built from the same tokens, no new colour): the choice buttons, the paper row, the tick row, the banner,
   the flag block (Stop and Check by hand), the readers table and the sample banner. */
