This output is already presentation-ready; don't reformat it with another AI step.

## Authentication and enablement

No integration. Default-on.

## Inputs

* `file_url` **or** `text` (one required): PDF, image, or spreadsheet via `file_url`; raw text via `text`.
* `dimensions` (required): array of `{name, categories, allow_multiple?}`. `allow_multiple: false` forces single-select on that dimension; omit or `true` for multi-select.

## Output

Per-dimension classifications in a display-ready format.

## Limits and side effects

* Spreadsheets are classified from parsed cell text.
* No external writes.

## Expected errors

* Neither `file_url` nor `text`.
* Empty or malformed `dimensions`.
