/* seedanceflash.com, "Timing Board" (the owner's pick of three redesigns, 2026-11-12;
   all three stay browsable at aigalaxy.app/early-looks/seedanceflash-redesign/).
   A benchmark / race-timing look built around the measured run times: cool graphite
   with a faint chart grid, hard edges, one signal orange that means "measured", giant
   tabular timing digits, and the lap board running the full width of the home page
   with a tick for every minute. Every wait time in every table also gets a bar
   (../foot.html). Headlines are Montserrat, self-hosted (SIL OFL 1.1, OFL-montserrat.txt)
   in the four subsets the site's Latin and Cyrillic languages need; everything else is
   the system font. Estimates stay sky blue with dashed edges and hatched bars (the copy
   says "Blue boxes are our estimates"), so a number we guessed never looks measured.
   Avoids ByteDance, Dreamina, CapCut and BytePlus looks: no blue to violet gradients. */
