   Client logo marquee — two-track pattern (not a single max-content-width
   block scrolled by -50%). That approach depends on the browser correctly
   computing `width: max-content` on a flex row with 26 children, which is
   exactly the kind of layout some mobile browsers get wrong or compute
   late — resulting in the animation running against a 0/incorrect width
   and never visibly moving. This version sidesteps that entirely: two
   identical tracks sit side by side in a flex row, each one independently
   translates by -100% of ITSELF (never a shared/computed total width), so
   there's nothing fragile to mis-measure. Same animation on both tracks
   means track 2 is always exactly where track 1 started when it loops,
   so the seam is invisible.
