Restyle post cards with Phosphor icons, colored engagement counts, and rank numbers
Use Phosphor Icons (fill + bold weights via CDN) for heart and repeat icons
throughout the app. Color the active engagement metric (red for likes, blue
for reposts) and keep the secondary metric muted. Move rank numbers to the
left as small labels, highlight the #1 post with a subtle background tint,
and format counts with locale-aware comma separators. Update CSP to allow
jsdelivr.net for stylesheets and fonts.
