## Isometric drawings

The sources of `references/isometric.md` and `references/isometric-recipes.md`, as the isometric skill listed them through 2026-10-07:

- Prototemplate: DESIGN.md sections 2 (the line law and the auditor's blind spot for SVG), 6 (the isometric family), 7 (the 1-bit language), 9 (motion discipline and the dash rules) and 14 (the two read lines).
- Prototemplate: BRAND.md section 4 (marks as alpha masks, the shimmer as the one flourish), section 5 (the accent and its dark-band lift), section 8 (where the identity ships, with the Dossier, `/d/singularity-dossier`, as the direction the site grew from) and section 9 (the direction line and the avoid list, including glassmorphism).
- Prototemplate: `src/app/d/toolchain/diagrams/iso.ts`, `IsoSolid.tsx`, `IsoFrame.tsx`, `iso.css`, `DitheredMark.tsx` and `tc-stack-iso.tsx`.
- Prototemplate: `src/app/d/_v0/sections/Locadex.tsx`, `locadex.css`, `StackTower.tsx`, `FullStack.tsx` and `fullstack.css`; the production copies in `src/app/d/production/sections/`.
- Prototemplate: `src/app/d/toolchain/enterprise/GovernedColumn.tsx`, `src/app/d/toolchain/locadex/LocadexIso.tsx`, `src/app/craft/IsoDemo.tsx`, `src/app/craft/craft.css` and `src/app/craft/libraries.ts` (the kit entry shown on /docs).
- Prototemplate: `deck/slides/35-iso.html` (the brand deck's iso slide) and `docs/figma-v0-spec.md` (Locadex is an isometric diagram, never a gif).
- Prototemplate, local: `motion/films/blog-designing-docs/index.html`, the bridge block (round 7d).
- gt-cloud: `apps/landing/src/components/landing/shared/iso.ts`, `DitheredMark.tsx` and `DitheredLedgerMark.tsx`; `apps/landing/src/components/landing/sections/fullstack/StackTower.tsx`; `apps/landing/src/components/landing/sections/locadex/Locadex.tsx`; `apps/landing/src/components/pages/pricing/PricingStackDiagram.tsx` and `pricing-page.css`; `.agents/skills/gt-landing/references/design.md` (the landing's code map).
- Kevin, 2026-08-04: the first v0 build's only approved element was the Locadex animation, which "should have the locadex logo on it"; Locadex is never a gif.
- Kevin, 2026-08-11: the k/ pages restart. Pricing had "nothing redeeming but the isometrics"; marks are seated as alpha masks (the small PNG assets, never a flat logo overlay); seated words at chip scale are illegible.
- Kevin, the tower and Locadex rounds of 2026, quoted in the comments of `StackTower.tsx`, `FullStack.tsx` and `Locadex.tsx`: tags lie on the layers, the scanner stays inside the slab, the shimmer crosses the whole mark, the warm-to-accent pulse read as flashing, the top plate full size, no words by the diagram, the figure never moves down.
- Kevin, 2026-10-02: bring the isometric view back into the designing-docs film as a bridge, replacing nothing.
- Kevin's memory notes in Claude Code: `redesign-v0-verdict` (2026-08-04), `k-pages-restart-round` (2026-08-11, the seated-mark technique) and `gt-motion-films` (the 2026-10-02 request and round 7d landing on 2026-10-03).

## Lines added on 2026-10-10 (system v2, lane L4)

- The isometric skill merged into this one: its body became `references/isometric.md` and its recipes `references/isometric-recipes.md`, with section numbers kept; section 10 of `SKILL.md`, the description's isometric clause and the `isometry` area summarize it. Plan section 2.2 (the isometric skill merged into gt-diagrams; only the Locadex iso survived review, memory note `redesign-v0-verdict`) and lane L4 in plan section 5.4. The old skill's URL and every path under it redirect to `/skills/gt-diagrams` (308, `next.config.ts`).
- Section 2's lookup table and the live-component list moved to `references/components.md`, section 7's dash traps to `references/dashes.md`, section 3's fill lint detail and accent table to `references/color.md`, and section 9 to `references/checking.md`, unchanged, with summaries left in `SKILL.md`, to keep the body under the 24,000-byte budget (plan section 2.2).
- Related skills: `gt-verify` replaces `agent-browser` as the live check (inventory `skills.json` row 38, plan row N-28).
