   SERRES DRIVE — fleet-gallery.css
   "Mouse Scale Gallery" fleet listing: cars in pairs, the two panels of a
   row trade widths as the cursor crosses them (widths are driven by
   --fg-a / --fg-b, eased per-frame in js/fleet-gallery.js).
   Everything is prefixed .fg-  and uses only the tokens in css/styles.css.
   Default state = fully visible and usable; JS opts into the animated state.
