The `Mcu` → `Mtb` rename (#166, #169) covered the component, the hook and the config type, but left the shape of the value `useMtb()` returns untouched: it still handed back `mcuConfig`, `setMcuConfig` and `getMcuColor`. They are now `mtbConfig`, `setMtbConfig` and `getMtbColor`. The `mcu*` keys stay on the context value as `@deprecated` aliases holding the very same references, so existing destructuring keeps working until the next major. The `id` of the injected `<style>` tag stays `mcu-styles` — it is observable from user CSS and scripts, so renaming it would break selectors silently. Only the local binding follows the rename.
