/* ---------- mobile edge padding ----------
   NOTE: the winning mobile padding override lives at the END of each page's
   own <style> block, because a page's inline styles load after this shared
   sheet and would otherwise override a rule placed here. Keep that override
   in sync across pages (currently: 1.4rem left/right at <=560px). */
