One of five: the boards that had not yet adopted the shared theme (PyAutoBrain#262, which drew each organ's logo glyph as the hero mark). Siblings: PyAutoHeart, PyAutoHands, PyAutoScientist.

The knowledge board carried its own copy of the GitHub-grey stylesheet — a plain <h1>, dark-only, GitHub-blue links, and one violet pill that was the only trace of the logo it sits under.

What changed

• Renders through the Brain's board/_theme.py: the hero (the book and node-tree mark, the wordmark, the hairline-and-dot rule, the tagline), the accent as link and heading colour, and a count strip carrying pages, cited, to-cite and queued.
• Imported, never copied. knowledge_board.yml and validate.yml check PyAutoBrain out beside this repo; a local run resolves $PYAUTO_BRAIN, either checkout path, or $PYAUTO_ROOT (default ~/Code).
• Only the html surface calls the theme — --md, --badge and --json are untouched.
• What the shared sheet has no opinion on stays here — the citation bar, the collapsible queue sections, the paper filter, the read-rate sparkline — rewritten against the theme's variables so this board follows the family accent instead of setting a second palette.
• Copy chips move to the family's delegated handler (data-cmd); the one thing that needed saying is that a chip inside a <summary> must not also toggle its section.

Verification

• pytest tests/ -q — 28 passed, including a new test asserting the page carries this board's mark, tagline and accent and that the old hard-coded #58a6ff is gone. validate green in CI.
• Page rendered and screenshotted from this repo's real content.

A sibling's CI caught one thing (second commit): the first resolver spelled its last fallback ~/Code/PyAutoLabs/PyAutoBrain, and the tenant firewall rightly rejects an org name in organ code. It reads $PYAUTO_ROOT instead — same resolution, no instance fact.
