/* ============================================================================
   ZPad — "Field Manual" design system (v2, 2026 redesign)
   ----------------------------------------------------------------------------
   Direction: technical-editorial. Warm ivory paper, near-black ink, one
   vermilion signal color. Fraunces display serif + Geist UI + Geist Mono
   labels. Hairline rules, datasheet numbering, ink CTAs. The live product
   demo panel keeps its own dark app chrome (defined per-page, not here).
