/* ===========================================================================
   Excise PDF — excisepdf.com

   Light theme, on purpose: this is a documents product, so the page is paper
   and the one high-contrast surface on it is the receipt (positioning brief,
   locked decision 3). Every colour below is sampled from
   assets-src/icons/excisepdf-icon.png — the slate mat (#3c4d69 / #162133), the
   excised bar (#1d2636), the icon's paper (#fbfcfd) and its two greys.

   Structure follows rangefinderinvest/styles.css (its class vocabulary,
   its reveal/skip-link/focus rules); the palette and the sections are this
   site's own. No blackout-bar motif anywhere — the product's argument is that
   a black box is a drawing, and leading with one sells the thing it refuses
   to be (docs/NAMING-USAGE.md, "Never").
