/*
 * Datasheets: the one-pagers for the Pentagon of Pain and METEORSTORM.
 *
 * Written 10 October 2026, after visitors described the Space ISAC page as
 * "AI slop": dark rounded cards, glowing pills, letter-spaced micro-labels,
 * click-to-read tab widgets. These sheets go the other way on purpose. They
 * are set like an engineering datasheet: white paper, black ink, hairline
 * rules, numbered figures with captions, everything readable without a click.
 *
 * One sheet is exactly one US Letter page when printed (and when the PDF is
 * made by scripts/one-pager-pdf.mjs). On screen the same sheet sits on a desk;
 * below 760px it reflows to one column.
 *
 * Colour carries meaning only in METEORSTORM figures, where each layer has its
 * colour from the METEORSTORM visual language. Everything else is ink.
