## Features

- The press — the page exists as two settled sheets (paper and ink) and a brayer's slanted edge reveals one over the other, so nothing on the page or the control ever tweens
- The real control sits under its inked copy; hover, press and focus are mirrored onto the copy with :has(), and the letterpress plate (a hard offset slab) inverts with the sheet
- Radius follows the system: card role for the plate, switch-track role for the rail, concentric knob; 2px rules on the 3:1 accent tier per sheet
- WCAG AA measured on both sheets at rest and mid-sweep: title/copy/eyebrow/status ≥4.5:1, choices ≥4.5:1 on the card, rules/knob/plate ≥3:1, on all published systems; live status region; reduced motion
