/* Sentinel Media, shared chrome: tokens, type, nav, buttons, footer.
   Page-specific components live in each page's own <style> block.

   Shape rule (documented so it stays consistent):
     cards + panels 24px, app icons 22.5% (iOS squircle approximation),
     buttons / chips / status pills fully rounded, inputs 12px.
   Colour rule: Sentinel gold is the only interface accent (buttons, links,
   focus, selection). App colours belong to the apps and appear only on
   their own cards, icons and pages. No multi-hue gradients on this site. */
