/* iPhone SE class (≤ 380 px viewport). Playbook Часть 13 specifically
   calls out 380 px as the QA target — anything that fits here fits 99 %
   of phones. The default rules already collapse to single-column at this
   width via the 768 px breakpoint; what we tighten further:
     • side padding shrinks so content doesn't get squeezed out by gutter,
     • the hero H1 drops one notch — at 48 px it overflows on 375 px iPhones,
     • CTAs and chips compress so they don't wrap awkwardly,
     • table cells lose extra padding (data density becomes painful otherwise),
     • the trial-banner CTA wraps under instead of fighting for inline space. */
