 - Local GitHub Actions reproduction already has a baseline helper at `scripts/act-ci.ps1`, using `ghcr.io/catthehacker/ubuntu:act-latest` for `pull_request` runs.
 - Household IDs in shared-fixture API tests must be unique across test classes to avoid cross-test contamination.
+- Tailwind v4 in `src/ui/web` should be wired through PostCSS, and `@tailwindcss/forms` should use `strategy: "class"` to avoid reset regressions during the design-system rollout.
+- Storybook foundations can preview Latte and Mocha together by scoping Menlo's semantic CSS variables on per-story containers instead of relying on global `html.dark`.
+- `src/ui/web/projects/menlo-lib/package.json` must point `types` to `types/menlo-lib.d.ts`; otherwise Vite dev overlays report `TS2307` for `menlo-lib` imports even when the dist package exists.
+- `mnl-page-shell` should own the router-driven scroll reset while `mnl-tab-bar` keeps both mobile and desktop nav DOM trees mounted so CSS alone controls the responsive switch.
+- Angular partial-compilation builds for `menlo-lib` can only bind to protected/public component members from templates; private signals break `ng-packagr` builds.
+- `pnpm test:e2e` reuses any existing dev server on port 4200; kill stale `nx serve menlo-app` listeners before rerunning Playwright if a Vite overlay appears from old type-resolution errors.
+- `src/ui/web/projects/menlo-lib/src/index.ts` and `src/public-api.ts` need to stay aligned when adding new exported molecules, or Storybook/dev imports drift from the packaged surface.
+- Design-system gradients that must work in app runtime, Storybook previews, and Vitest are safest when driven by shared theme CSS variables instead of `light-dark()`.
+- `mnl-button` exposes routed CTA interactions through its `pressed` output, so components that need navigation should handle routing in the host component instead of trying to attach `routerLink` directly.
+- `pnpm exec nx test menlo-app --coverage` can fully cover a migrated app slice while still failing branch-wide because `menlo-app` and `menlo-lib` both enforce 100% global coverage across pre-existing uncovered files.
+- A stray `Menlo.Api.exe` process locks backend build outputs and makes `dotnet test Menlo.slnx` fail even when the test suite itself is green; stop the specific PID before rerunning.
+- `mnl-form-layout` needs explicit `[mnlFormTitle]` and `[mnlFormActions]` projection slots with the middle content slot excluding them, or Angular's wildcard projection swallows the sticky action bar content.
+- `ng-apexcharts` 2.4 ships a standalone `ChartComponent` (`apx-chart`), and Menlo chart helpers should keep `ng-apexcharts` plus `apexcharts` in `peerDependencies` when exporting typed chart utilities.
