 ## Branding
 
-The theme implements the Lab271 brand kit (`labs-branding`, in particular
-`brand/visual-identity.md` and `brand/tokens/lab271.tokens.json`). When touching
-colors, type or the marks, read those first. The rules that shaped what is here:
+The theme implements the Lab271 design refresh (see ADR-0005 in
+`Lab271/www.lab271.io`), which supersedes the `labs-branding`
+(`brand/visual-identity.md`, `brand/tokens/lab271.tokens.json`) Navy/Primary
+Blue/Teal system this site carried before. `labs-branding` has not been
+re-derived from the refresh yet, so it is temporarily stale - treat this
+repo's `custom.css` and its `www.lab271.io` sibling as authoritative in the
+meantime. The rules that shaped what is here:
 
-- **Palette.** Navy `#1A1F36` anchors dark surfaces, including the nav bar in
-  both color modes. Primary Blue `#6C8EEF` is the signature, Blue Light
-  `#A8C0FF` its gradient partner. Teal `#36C5B0` is a spark: at most one per
-  composition, which here is the rule in the badge. Never pure black.
+- **Palette.** Near-black `#020C17` anchors dark surfaces, including the nav
+  bar in both color modes (never pure black). Cyan `#1EE8ED` (dark mode) /
+  `#18B9BD` (light mode, darkened for contrast) is the signature accent.
+  Orange `#FF7000`/`#FF8D33` is a spark: at most one per composition, which
+  here is the rule in the badge. Light mode's canvas is a warm paper off-white
+  (`#FAF9F5`), not a cool gray.
 - **Type.** Inter and JetBrains Mono are the open stand-ins for TT Interphases
   and TT Interphases Mono, the licensed SBP faces that cannot ship on a public
-  build. Sentence case headings with tight tracking. Mono is "a pinch of tech",
-  so it is limited to the `e = 2.71828` motif and the language labels.
-- **Marks.** `logo.svg` and `badge.svg` set Inter outlined to paths, so they
-  render without the font installed. The badge follows the brand kit's concept A,
-  "the door plate". Change them by editing `scripts/refresh-marks.py` and
-  re-running it, not by editing the path data.
-- **Written "Lab271"**, sentence case, no space. Never "LAB271".
+  build - unchanged by the refresh. Sentence case headings with tight
+  tracking. Mono is "a pinch of tech", so it is limited to the `e = 2.71828`
+  motif and the language labels.
+- **Marks.** `logo.svg` and `badge.svg` are vendored directly from the design
+  team's final artwork for the refresh, not generated - the previous
+  Inter-outlined-to-paths approach (`scripts/refresh-marks.py`) is retired.
+  Update them by replacing the SVG file with a new export from the design
+  source, not by hand-editing the path data.
+- **Written "Lab271"**, sentence case, no space, in all prose and copy. Never
+  "LAB271" in running text - the all-caps treatment is reserved for the
+  wordmark graphic itself (`logo.svg`).
 - US English throughout.
 - No em dashes in the copy. `docs/scripts/refresh-repos.mjs` normalizes them out
   of upstream GitHub descriptions too.
