   MOBILE COMPACT LAYOUT — phones (< 768px)
   Purpose: cut the total scroll length of every page on a phone.
     · product cards  -> two-up, 150px image band, trimmed copy
     · page heroes    -> ~215px media, title capped at 23px
     · inner sections -> reduced padding, shorter placeholder bands
   Many declarations carry !important deliberately, for two reasons:
     1) the card frames carry inline aspect-ratio / min-height, and
     2) each page ships its own <style> block that is parsed AFTER
        this file, so a normal rule here would lose the cascade.
