   Page heroes ("Home › Resources" bands) — the launching-page look:
   deep navy, dotted texture, drifting orange/violet glows and faint
   concentric rings. Loaded after every page stylesheet so it wins.
   Applies to .page-hero (notices, resources, team, about, course
   locator, details) and the newer .gl-hero / .ss-hero variants.
