### Bug description

For all user-facing length specifications, please refrain from supporting dimensionless numbers implied to be inches.

Do support numbers only when combined with explicit units of measurement, such as `10in`, `17cm`, or `150mm`.

(Including, but by no means limited to `page-width`, `fig-width`, `fig-height` …)

Please do follow the examples of TeX/LaTeX, pandoc, and pretty much every text processor (MS Word, LibreOffice, Pages, etc.) there is in this respect.

### Checklist

- [ ] Please include a minimal, fully reproducible example in a single .qmd file? Please provide the whole file rather than the snippet you believe is causing the issue.
- [ ] Please [format your issue](https://quarto.org/bug-reports.html#formatting-make-githubs-markdown-work-for-us) so it is easier for us to read the bug report.
