/*
|
|
* Capture a single docs page to PDF, applying the brand-aligned print
|
|
* stylesheet. Used both for on-demand single-page PDF (the per-page
|
|
* "Download PDF" button) and as the unit primitive that the book
|
|
* builder concatenates.
|
|
*
|
|
* Usage:
|
|
* node pdf/scripts/build-page-pdf.mjs <url> <output.pdf>
|
|
* node pdf/scripts/build-page-pdf.mjs http://localhost:3000/api pdf/build/api-overview.pdf
|
|
*
|
|
* Pre-req: the docs site is built (npm run build) and being served
|
|
* either by `npm run serve` or some other static server. Pass the URL
|
|
* the page is reachable at.
