   APPLICATION DETAIL PAGES (.page--application)
   Visual language inherits the homepage's aesthetic: dark navy hero,
   alternating section backgrounds, mono-annotated spec row, orange CTAs,
   full-bleed card images. Scoped so nothing leaks into other page types.

   WIDTH SYSTEM:
   - All sections use the standard .container (1200px max)
   - Reading content (narrative body, FAQ) sits in an inner .app-prose
     wrapper capped at ~720px for line-length comfort
   - Layout blocks (hero, grids, specs two-column, price card) use full
     container width
   ============================================================================ */
