This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. Ambiguous utilities like text-[var(--size)] and font-[var(--family)] resolve CSS variables to color and font-weight properties by default, requiring explicit length: or family-name: data-type casting to generate font-size and font-family declarations
  2. text-[--font-size] auto-wraps in var() and emits color, whereas text-[length:--font-size] emits font-size
  3. font-[--brand-font] emits font-weight, whereas font-[family-name:--brand-font] emits font-family
  4. bg-[--hero] emits background-color, whereas bg-[image:--hero] and bg-[length:--size] emit background-image and background-size
  5. border-[--line-width] emits border-color, whereas border-[length:--line-width] emits border-width
  6. bare underscores in arbitrary values convert to spaces while escaped underscores remain literal underscores
  7. math operators in calc() arbitrary values are automatically normalized with surrounding whitespace
