/*
 * Kit finder styles.
 *
 * Aligned to sterlingsep.com's own stylesheet so the finder reads as part of
 * that site rather than a bolt-on: the same palette, the same eyebrow and
 * divider treatment, the same card lift, the same system font stack. It does
 * not pull in Bootstrap: the finder is ~1000 lines of CSS with no framework,
 * and adding one to inherit six colours would be a poor trade.
 *
 * Brand is a rendering concern (spec §3), so everything brand-specific is a
 * token on the .theme-* class and nothing below it names a brand.
