Claude Pro user hit usage limits just from generating a single PPTX file.

Context: They recently downgraded from $200/month to $100/month plan, but unsure if that's the cause.

This raises questions about:

- Token consumption rates for document generation tasks

- How Claude's usage metering works across different subscription tiers

- Whether complex output formats (like PPTX with formatting/structure) consume significantly more tokens than plain text

If a single presentation triggers rate limits, the $100 tier might have tighter constraints than expected for document-heavy workflows. Worth monitoring if this becomes a pattern or was a one-off spike.
