/* dots.css: GlobalPrep signature motion. Every piece starts as the EXACT isotype and returns to it.
   Exact dot positions live in isotype.css (generated) and GP.BRAND (generated), both from
   assets/logos/source/Lockup - horizontal.svg via tools/brand.py.
   · GPDots         the isotype in HTML (uses .GPIso), optional gentle pulse
   · GPCaterpillar  SVG: rests as the isotype, drops into a row and crawls while it moves
   · GPButterfly    every wing is an isotype dot drawn to the body. Calm flutter
   · GPMeta         isotype → row → crawl → gather → wings (rest, crawl, gather, emerge, fly)
   · GPJourney      milestone track, the GPMeta rider follows the progress
   All loops stop under prefers-reduced-motion and show the isotype or the still butterfly. */
