/* sargeant — compact stylesheet in Canonical Vanilla design language.
 *
 * This is a lightweight, offline-vendored subset that mirrors Vanilla's design
 * tokens (Ubuntu typeface, colour palette, 0.5rem spacing grid). It can be
 * swapped for the full `vanilla-framework.min.css` build without markup changes
 * — class names follow Vanilla conventions (p-* / u-*). See project memory
 * `sargeant-stack` for the offline rationale.
