 - **Runtime/tooling:** Bun, not Node. Use `bun install`, `bun run <script>`, `bun test`, `bunx`. Never `npm`/`npx`/`yarn`/`pnpm`.
 - **Build:** `tsc` emits `src/` → `dist/` (JS + `.d.ts`), then `scripts/post-compile.ts` runs. There is no Next.js, Vite, PostCSS config or `tailwind.config` in this repo - don't add them.
 - **Styling:** Tailwind v4 via `src/base.css` (`@import "tailwindcss"`, `@source "./"`, `@theme inline` tokens). `tailwind-merge` (`twMerge`) for class composition.
-- **Icons:** `lucide-react` (peer dependency).
+- **Icons:** `lucide-react` (peer dependency). Components take icons as elements. Nothing a component imports may look one up by name: `LucideIcon` (`import * as icons`) puts all of lucide in every bundle of an app that reaches it, since bundlers can't tree-shake a namespace lookup, so only an app's own pages may import it.
