   Sentinel Systems — homepage refinement layer (v41)
   Loaded last on the homepage. Goals:
     * calmer, more professional composition (tighter rhythm, cleaner edges)
     * measurably lighter paint cost — no giant animated blurs
     * consistent card language across hero, bento, steps, news and CTA
   Scoped to .home-pro so no other page is affected.
