docs/brand/ gets the same set as Airlock's and Sherpa's, drawn the same way: the tile, stroke and round caps, ink and paper, Space Grotesk / JetBrains Mono as paths. The mark is a small graph, three nodes and three edges in ink, with the node that answers in indigo. The indigo keeps PHP's #777BB4 hue: #4F57C4 on paper (5.5:1), #989DE1 on ink (7.1:1).

Both READMEs open with the lockup, with a dark variant, instead of the banner. docs/phpgraph.png stays: the README of every tag (v0.1.0 to v2.0.0) loads it from main, so GitHub and Packagist would show a broken image for older versions.

After merging, set by hand: the social preview (Settings, General) and the avatar, from docs/brand/.

Minor · Functional Correctness · Quick win

Restore the project heading.

The change removes the phpgraph heading from both READMEs. The image alt text is not a heading, so readers who navigate by headings cannot find the project title. Restore a level-one heading, for example by placing the logo inside it. (github.com)
