/**
 * Canonical Sentinel — page styles
 *
 * The scan UI was originally authored against the older w3c-functional token
 * set (square corners, hairline #2a4a6e borders, #f5f5f5 fills). The rest of
 * the site now runs nrlc-editorial-system, which only force-adopts generic
 * class names (.btn, .content-block) via !important. The tool's private class
 * names were never adopted, so the results view rendered in the old language
 * while the hero rendered in the new one. These rules move the tool's own
 * components onto the --nrlc-* tokens so both halves of the page agree.
 */

/*
 * The shared design system is already loaded by templates/head.php.
 * Importing it again here caused the primary navigation to reflow after the
 * page-specific stylesheet loaded.
