The README opened with a plain # Trinity and one badge. It now opens with the project's mark.

The logo

docs/assets/trinity-icon.png — the logo already in use on the platform's other project, copied in rather than reinterpreted. Resized from 1024px and stripped of metadata: 1.5 MB down to 182 KB.

The wordmark

Block letters on a 37×5 grid, emitted as one rectangle per run of filled cells rather than as text. No font is involved, so it renders identically wherever it is shown and stays sharp at any size, and the neon gradient is taken from the logo so the two read as one mark.

Both horizontal and vertical runs are merged. Emitting a cell at a time left the glow filter scalloping the edge of every vertical stem — visible in the first render, fixed before it shipped.

Responsive by having two compositions

Not by hoping one scales. The wide mark carries outer padding; the narrow one, served under 600px by a <picture> element, runs edge to edge — on a phone the mark is scaled to the viewport, so padding is width the letters could have used.

Verified by rendering it in a browser at desktop and phone widths, on GitHub's dark ground and on white, rather than by looking at the file. ImageMagick's internal SVG renderer drops the gradient and the filter entirely, so checking with it would have proved nothing.

Also in the header

The badge row (OpenSSF silver, gate status, licence, runtime), the one-line statement of what Trinity is, and links to the five documents a reader wants first: quick start, architecture, security model, assurance case, roadmap.

Corrected while here

The status line said 25 slices. There are 26 — the supply chain slice landed after that sentence was written.

Evidence

mix gate exit 0; 576 passed, 18 excluded; coverage 80.31%.
