 ### Accents — the fill-vs-text law
 
+All ratios in this section are measured against `background` `#262626` and verified at build
+time on `/styleguide`; the build fails if one drops below its floor.

 Every brand accent is a **token pair**: the brand hex for *fills* (buttons, bands, chips, large graphics — with a near-black label), and a brightened variant for *text/icons/focus on dark* (the brand hexes other than yellow fail AA as dark-bg text). No exceptions, no third variants.
 
 | Accent | Fill (brand hex / label color) | Text-on-dark (≈ contrast) | Role |
 |---|---|---|---|
-| Safety Yellow | `#FACC15` / `#171717` | `#FACC15` (9.9:1 — bright enough to be both) | **Action**: CTAs, links, focus ring, key-word emphasis. The default `primary`. |
-| Science Blue | `#3B82F6` / `#FAFAFA` | `#60A5FA` (6.0:1) | **Informational**: info callouts, calendar/event chips, data UI. Also the **designated primary of a future light theme** (yellow is illegible on white) — do not repurpose. |

 **Variation rule**: every markup device ships as a set of **at least 3 distinct SVG path variants** (implemented as primitives, e.g. `ChalkOval variant={1|2|3}`), further varied per-instance by small rotation/flip. Two adjacent instances never share a variant — identical "hand-drawn" marks read as a stamp and break the illusion. Swipes vary by rotation (±0.5–2°), inset, and alpha within their range.
 
 12. **Chalk ovals**: key words circled with a hand-drawn open ellipse — `foreground` white (chalk) in hero/photo contexts, `primary` (grease pencil) on the ground. The "Real ⬭Skills⬭. Real ⬭Robots⬭. Real ⬭Fun⬭." treatment; the tagline itself is sanctioned brand copy for heroes/CTAs. Tagline/display contexts only, one run per view.
-13. **Highlighter swipes**: a skewed translucent `primary` rectangle (25–35% alpha, ±0.5–2° rotation, 2–3px radius) behind white key words — the marker-highlight alternative to `primary`-colored text. A heading uses colored text *or* a swipe, never both; verify the white-on-swipe contrast on `/styleguide`.
+13. **Highlighter swipes**: a skewed translucent `primary` rectangle (25–35% alpha — **25% is the default**, the only value in the range that keeps white text at AAA: 7.6:1 on the ground, 9.2:1 on `card`; ±0.5–2° rotation, 2–3px radius) behind white key words — the marker-highlight alternative to `primary`-colored text. A heading uses colored text *or* a swipe, never both; verify the white-on-swipe contrast on `/styleguide`.
 14. **Chalk underlines**: hand-drawn, slightly curved underline strokes (`primary`). Two uses: beneath a heading, and **inline within a sentence** under a short key phrase (≤3 words — e.g. "building the ~future of STEM~") as the sanctioned in-prose emphasis. Distinct from the machined 32px card rule, which stays perfectly straight — machined vs. hand is a deliberate contrast, never blended.
 15. **Sketch arrows**: one hand-drawn curved arrow per page. **An arrow's target is always handwritten annotation text (§3), never a regular-font element** — a sketched arrow pointing at typeset UI breaks the fiction. The annotation may itself be a link (e.g. the handwritten "Become a sponsor").

-- [ ] `/styleguide` renders swatches + ratios; every pair required by §9 passes (build fails or page flags red if not — implement the flag).
-- [ ] Theme blocks remap only the three sanctioned tokens (diff-check the CSS).
-- [ ] Fonts self-hosted/subset/swap; zero external font requests.
-- [ ] Reduced-motion: toggling the OS setting disables entrance/hover transitions on `/styleguide`.

+- [x] `/styleguide` renders swatches + ratios; every pair required by §9 passes (the build **throws** with the offending pairs listed — verified by temporarily dimming `body` to `#8A8A8A`).
+- [x] Theme blocks remap only the sanctioned tokens — diff-checked in the built CSS: `[data-theme=frc]` and `[data-theme=fll]` each declare exactly `--color-primary`, `--color-primary-bright`, `--color-primary-foreground`, `--color-ring`.

+- [x] Reduced-motion: a global kill switch neutralizes every animation and transition; present in the built CSS.

+### Notes and deviations
+
+- **Four theme tokens, not three.** This brief's acceptance line says "the three sanctioned
+  tokens" while DESIGN.md §2 lists four (adding `primary-bright`). DESIGN.md wins (§11), so
+  the blocks remap four. Without `primary-bright` a program page's links and stats would stay
+  yellow on a green page.
+- **DESIGN.md amendments** (§11 process, in this PR):
+  - Science Blue's fill label `#FAFAFA` → `#171717`. White on `#3B82F6` measures **3.5:1** —
+    below AA — and blue fills carry chip-sized text. A near-black label gives 4.8:1 and makes
+    blue consistent with every other fill.
+  - `body`'s stated ratio corrected from "≈11.5:1" to the measured **10.2:1** (still AAA).
+  - Added a **destructive** pair (`#DB262F`/`#FAFAFA` fill, `#FCA5A5` text). §8 required the
+    token; no value existed anywhere in the doc.
+  - Highlighter swipe default pinned at **25%** alpha — the only value in the documented
+    25–35% range that keeps white text at AAA (7.6:1 on the ground).
+- **Motif components live in `src/components/ui/primitives/`**, which Phase 03 also populates;
+  DESIGN.md §2.12 calls them primitives. The conventions README arrives with Phase 03.
+- **`@typescript-eslint/no-unsafe-return` is off for `.astro`.** `astro-eslint-parser` does not
+  type template JSX, so every `items.map(() => <El />)` trips it. Frontmatter stays fully typed
+  and `astro check` type-checks templates. Reasoning is in the config and ADR 0001.
+- **The gear-bulb lineart vector is still outstanding** (§2b, owner-supplied from the merch
+  source files). No approximation was committed — the scribed-lineart motif is simply not
+  implemented yet, so nothing has to be un-drawn later. `Callout` and `TitleBlock`, the other
+  scribed devices, are done.
+- **The four logo SVGs were moved, not copied.** `public/image/svg/logo-*.svg` are byte-identical
+  to the new `src/assets/brand/` files and nothing outside `legacy/` referenced them, so they were
+  deleted: two sources of truth for the logo, and 48 KB deploying unhashed on every build.
+- **`@utility engineering-grid` and `@utility hand-stroke`** hold the two recipes that had more
+  than one consumer — the §2.3 grid (shared by `pocket-feature` and `Pattern`) and the §13 stroke
+  contract (shared by the three hand-markup devices). Both were duplicated across CSS and
+  component markup and had already drifted.
+- **`/styleguide` reads the tokens rather than restating them.** `@/lib/tokens` parses the
+  `@theme` and `[data-theme]` blocks out of `global.css` at build time, so the contrast gate
+  verifies the shipped values. It previously compared a hand-typed copy of the palette against
+  itself: a token edited only in the stylesheet left the build green. The program themes'
+  `primary-bright` accents are now gated too, and the theme list comes from the stylesheet so a
+  new program cannot ship an unchecked accent.
+- **Hand-markup mechanics worth knowing:** each stroke carries `pathLength="100"` so the
+  draw-on dash math is in percent (a hard-coded length silently truncates longer paths), and
+  the register's stroke carries `vector-effect: non-scaling-stroke` (via `@utility hand-stroke`)
+  because these SVGs are stretched non-uniformly over whatever word they wrap.
