   Be Savage — design system
   ----------------------------------------------------------------------------
   Brand is fixed by the iOS app: Montserrat, lime #D5FF08 on near-black. The
   site's point of view: this product MEASURES rotation, so the page is built
   like an instrument readout. Montserrat carries voice; JetBrains Mono is
   reserved strictly for measured values + telemetry labels (never body), so
   every number reads like a HUD. Amber #FFB347 (the app's real off-target
   verdict colour) is the second voice, keeping it off the mono-green cliché.
   Token NAMES are kept stable (--bg, --lime, …) so per-page inline styles work.
