Testing & QA

• Replaced 27 font sizes with a 6‑step scale

  Replaced 27 rendered font sizes whose nearest neighbours were 0.6% apart with a six‑step Major Third scale, and wrote the linter that fails the twenty‑eighth.

• Closed the colour system at 28 colours

  Closed the colour system at 28 documented colours with a linter that fails a value painted but undocumented, documented but unpainted, mis‑measured, respelled as a literal, or within a perceptual distance of 0.02 of one already there.

• Fixed a sitemap with one shared timestamp

  Fixed a sitemap where 172 of 176 URLs shared one modification timestamp, by taking the date from git history after establishing that the export rewrites every file on every run.

• Built a 48‑token macOS design system

  Built a 48‑token design system on the platform's own glass material and wrote the linter that rejects a magic number, a hardcoded font size, or an animation that ignores the reduce‑motion preference.

• Built the visual identity from 2 drawings

  Built the company's icon and favicon sets from two hand‑made drawings, with every derived asset regenerated by script and a check that fails when a derived file was committed before its source.
