 - Default `guidelinesGlob` swept 46 repo process docs into `guidelines/` —
   the config pins a curated 5-file design set; keep it curated.
 
+## Known claude.ai/design validator findings (accepted, do not "fix")
+
+From the July 2026 design-side review (CLAUDE_CODE_FIXES.md): the design app's
+validator flags on our compiled-Tailwind output that are heuristic noise, not
+repo defects — re-flag to the design agent instead of restructuring CSS:
+
+- "56 unregistered component-scoped custom properties" — all `--tw-*` Tailwind
+  runtime vars + `--footer-scrim-height` (component-local by design).
+- "126 pseudo theme scopes" — Tailwind utility classes misread as themes.
+- README token count vs stylesheet count — converter/validator counting
+  difference (`317 defined` includes non-`:root` definitions).
+- `--text-hero` font-family misparse — mitigated 2026-07-14 by adding the
+  `--text-hero--line-height` companion; if the warning persists it is
+  design-app-side.
+
 ## Known render warns
 
 - None — 10/10 render clean, no thin/blank/variantsIdentical flags.

+## Icons
+
+The bundle ships a curated lucide icon set — import icons from the package
+itself, never from `lucide-react` (it is not available to designs): `Search`,
+`SearchX`, `FileText`, `File`, `Inbox`, `Upload`, `Download`, `ShieldCheck`,
+`ShieldAlert`, `TriangleAlert`, `AlertCircle`, `Ban`, `X`, `Check`,
+`CheckCircle2`, `Info`, `Loader2`, `ChevronDown`, `ChevronRight`, `ArrowLeft`,
+`ArrowRight`, `Plus`, `Trash2`, `Pencil`, `Filter`, `Settings`, `Database`,
+`BookOpen`, `Stethoscope`, `HeartPulse`, `Pill`, `Calendar`, `Clock`,
+`ExternalLink`, `Copy`, `Maximize2`. The `icon` prop on `PanelHeading` /
+`EmptyState` is optional — omit it rather than inventing an icon.
+
 ## Where the truth lives
 
 Read `styles.css` for the full token set (`:root` and `.dark` blocks) and each
-component's `.d.ts` + `.prompt.md` for its API. Icons are `lucide-react`
-components passed as the `icon` prop where accepted.
