   POL — responsiveness layer
   Loads AFTER pol.css / pol-scenes.css / pol-home.css so it can
   override their breakpoints. Three concerns:
     1. Laptop midrange (901–1280)  — stop the rail/headline collision
     2. Ultra-wide (≥1380)          — align hero + nav to content column
     3. Mobile (≤900)               — rebuild the hero (no scroll-jack)
                                       with 3 switchable modes + data density
