Instruments

Working tools built on the system — measure contrast, watch the leaf find the light, resize the room.

Instrument 1

Contrast Lab

Pick any two color tokens and read the live WCAG ratio — the math is hand-rolled (website/lib/contrast.ts), not a library.

Seeing is only the beginning.

AAA

AA requires 4.5:1 for text, 3:1 for graphic/focus elements; AAA requires 7:1.

Instrument 2

Leaf + light demo

Two states of the same geometry, side by side: seeing (sun present, static identity) and searching (bare leaf, pulsing, loading only) — plus the mark’s horizontal light axis.

Seeing

Sun present. Static identity — mark, monogram, favicon, app icon.

Searching

Sun absent, leaf pulsing. Loading only — never shipped static.

The pupil doctrine’s successor (ADR-0011): the sun present means the instrument sees; its absence, with the bare leaf pulsing, means the instrument is searching. Adding a sun to the loading loop, or shipping the bare leaf at rest, are both misuses (docs/LOGO.md). The dashed line is the flare’s horizontal axis — the mark’s light direction, replacing the retired 45° aperture axis.
