Keep docs asset URLs repo-root-relative and pass images as literal MDX children so Mintlify can compile them through OptimizedImage under the /docs mount.
Mintlify's official guidance says: “Image paths are root-relative from your docs repository.” It also says relative paths such as `./screenshot.png` are unsupported. See [Image embeds](https://www.mintlify.com/docs/create/image-embeds).
The existing `/images/...` paths were correct. The failure came from passing them through custom-component string props, which kept Mintlify from seeing those images during its MDX transform.
- fix hero, building-block, and Slack avatar images
- preserve Slack avatar clipping
- normalize Hermes and Company Brain icon sizing
Tested with Mintlify validation, broken-link checks, and browser checks across every changed route.
