Replace the three near-identical public card primitives (ContentCard for
content pages, SectionCard for auth/account, and the new SurfaceCard) by
merging SectionCard into SurfaceCard, which now supports an optional header
(title/icon/action). Every remaining ad-hoc inline `rounded-2xl border`
card across (site) is converted to SurfaceCard, preserving each card's unique
visuals (background images, blur, gradients) via the style passthrough.
Net result: the public site uses exactly two card components — ContentCard
(CMS/content pages) and SurfaceCard (everything else) — and the shadcn Card
in components/ui/card.tsx is left untouched for admin.
Also deletes the now-unused components/home-section.tsx.
Introduce components/surface-card.tsx (Card + CardBody) mirroring the
.content-card / SectionCard token set, and use it on the (site) pages that
still hand-rolled card markup: me, search, and verify. This puts every
public page on one of the shared card components (ContentCard, SectionCard,
or SurfaceCard) for consistent radius/shadow/border.
