   AMBER & BARK — mobile.css  (v2 — complete rewrite)

   This file is the SINGLE source of truth for all
   responsive behaviour. It overrides everything in
   style.css, enhancements.css, polish.css, redesigns.css.

   Key fixes:
   1. Global overflow-x guard so nothing bleeds off-screen
   2. reveal-left/right clamped so translateX never causes
      horizontal scroll on narrow viewports
   3. Every section centred properly at each breakpoint
   4. Hero, products, story, grades, history, legacy,
      craft, origin, quality, contact, footer all fixed
