It's a pinning of bounded-systems/baobab: baobab is the design-system structure (no defaults); this repo supplies the values. One structure, many pinnings — the Bounded Systems org has its own (bounded-systems/brand); this is mine.

What's here

tokens/tokens.json — source of truth (W3C design tokens: primitive → semantic → recipe). Semantic roles are purpose-named (accent, status-negative, accent-ink, …), never hue-named — a recolor should never force a rename.
tokens/tokens.css — the emitted --bs-* custom properties (regenerate via tokens/build-tokens.mjs).
tokens/contrast.contract.json — this pinning's own pairs for bounded-systems/baobab's checkContrast / reusable check-contrast.yml workflow.
tokens/palette.pairings.json + tokens/token-a11y.json — the stricter WCAG+CVD+APCA palette gate (vendor/conformance-kit/gates/palette-gate.mjs, consumed by a downstream site's token-a11y.mjs). Known-failing, disclosed, not silently faked: 11 pairings currently fail CVD/APCA/non-text checks (e.g. accent on paper drops under 4.5:1 under simulated deuteranopia; several decorative divider/border pairings are well under the 3:1 UI floor). Fixing these needs real palette-value changes, not a rename — tracked as follow-up work, not done in the initial brick recolor.
css/base.css, css/fonts.css + css/fonts/*.woff2 — resets and self-hosted fonts: the IBM Plex superfamily (OFL), Sans for identity and UI, Serif for narrative prose, Mono for labels and identifiers, with css/fonts/LICENSE-OFL-IBM-Plex.txt shipped alongside the bytes. This is the axis on which this pinning diverges from bounded-systems/brand, which keeps Space Grotesk: two pinnings of one structure should not be typographically indistinguishable, and until #5 they pinned the same two families. One superfamily rather than three separate picks — Plex Sans / Serif / Mono share metrics and drawing, so the pairing is restrained by construction.
mark/, lockup/, favicon-32.png — the personal "r+d, door ajar" monogram, recolored to the brick accent.
content/strings.json + tools/{coverage,content,meta,a11y}.mjs — content-token catalog and the design-system coverage/meta/a11y checks a downstream site's CI calls directly.
