## Returns

`Promise`<`MessageContentItem`\[]>

## Remarks

The preview `.litertlm` models are text-in/text-out, and the exact multimodal content-item wire
shape is not yet stable in the published types. This maps image/audio/document/video to a
best-effort `{ type, path }`-style item when the matching modality flag is enabled, and otherwise
degrades through the shared `unsupportedMediaPolicy` (stash text / synthetic description / throw).
Verify the content-item shape against the installed `.d.ts` + a real multimodal model before
relying on the native path.
