   `:flexGrow="1"`, or `v-bind="someObject"` (object keys are preserved). `Box`/`Text`/`Static`
   bind a whole props/style object with `v-bind`; `Spacer` uses explicit camelCase.
-- **Name a component differently from any host tag it renders** (`BoxImpl`/`TextImpl`/
-  `StaticImpl` via `defineOptions`). vue-tsc 3.3.4 self-recurses a `<box>` tag to a component
-  named "Box" (it has no `isCustomElement` at the type layer). Public names (`Box`/`Text`/
-  `Static`) come from `index.ts`.
+- **Host primitive tags are `tui-`-prefixed** (`tui-box`/`tui-text`/`tui-virtual-text`/
+  `tui-static`/`tui-transform`), mirroring Ink's `ink-box`/`ink-text`. The prefix keeps the
+  renderer's intrinsic elements in their own namespace, so a template `<tui-box>` never
+  resolves to the public `<Box>` component — the components keep their real `name`
+  (`Box`/`Text`/`Static`) with no vue-tsc self-recursion. (Earlier the tags were bare
+  `box`/`text`/…, which collided with the same-named components and forced an `*Impl` internal
+  rename to dodge it; the prefix removed that workaround. vue-tsc has no `isCustomElement` at
+  the type layer, so a bare lowercase tag would PascalCase-resolve to the component — the
+  hyphenated `tui-` name sidesteps that entirely.)
 - **Don't reintroduce parent-walking or `parent.type.name` matching for context** — use
   provide/inject (`.name` is also fragile under minification).
 - **Don't force child-vnode inspection into a template** (the double-materialization wart). If
   a new component needs it, make it a render function — where the whole ecosystem draws the line.
-- The host elements (`box`, `text`, `virtual-text`, `static`, `transform`) compile to raw
-  element vnodes via the build's `isCustomElement` option and are an **internal** detail.
-  Consumers use `<Box>` / `<Text>`, never `<box>`. SFC templates may reference the host tags
