/*
 * Sylo hub chrome — always-on styling for the navigation regions Sylo injects
 * into content: the pillar "Explore {topic}" silo index, the cluster "Part of
 * {pillar}" back-link, and the Topics index page. These are elements Sylo writes
 * into post content, so the active theme has no selectors for them; this sheet
 * gives them sane spacing and a light, theme-agnostic treatment that inherits
 * the theme's own font and link colors (never hard-codes them). Low specificity
 * throughout so a theme can override anything.
