   Portable SSD & HDD buying guide (guides/portable-ssd-hdd-buying-guide.php)
   Loaded AFTER css/guides.css: reuses its .gd tokens, hero, buttons, callouts,
   tables and FAQ. Everything here is prefixed sg- (style.css owns generic
   names like .bar/.line, Bootstrap owns .row/.card).

   Animation contract: the base styles are the FINAL frame. The starting
   frame only applies while JS is running, motion is allowed and the figure
   has not played yet (.sg-js .sg-anim:not(.is-play)). So with reduced
   motion, or no JS, every diagram simply shows its finished state.
