~/display

Display.

One switch: the phosphor tube. Scanlines, barrel glass, a flicker you feel more than see — pure CSS, no JavaScript shipped for the effect itself.

~/display/crt

Phosphor tube is off.

Scanlines + barrel curvature + 1-frame text flicker + phosphor bloom.
Persisted in localStorage as crt; default OFF. Same toggle lives in the palette and the dock as crt.
Under prefers-reduced-motion the switch stays on but every CRT rule is hard-disabled — zero visual effect, structurally, not just dimmed.

~/display/scanlines

~/display/curvature

~/display/bloom

this is an approximation — flip the switch for the real tube
