/* ============ ANDROID APP PROMOTION ============
   Standalone stylesheet for the three Android app-discovery surfaces (homepage section, footer
   strip, mobile install sheet) — kept out of home.css/layout.css so the whole feature stays
   trivially reviewable/removable, same rationale as ads.css. Reuses existing tokens/utilities
   (theme.css) rather than introducing new colors, radii, or shadows. */
