/* ============================================================
   platform.css: Platform page (R17 rebuild, formerly technology.css).
   Renamed from /technology to /platform. Builds the GPS-for-Health
   hero schematic, the gap/biotyping morph, the three-technology
   cards, coordinate anatomy, biotypes-across-scales, the 14-disorder
   brain map, threshold-vs-trajectory, and the cross-scale depression
   flagship (with its adaptive focus marker). Every color/font/spacing
   value below is a var(--...) token already defined in styles.css /
   site-extend.css. Nothing here overrides them, only adds to them.
   One new token is introduced (--magenta) for sparing accent-only use,
   consistent with brand guidance that magenta is accent-only.
