/* ============================================================================
   Plow build-page design system — SHARED CHROME
   Single source of truth for the tokens, reset, buttons, chevron links, nav,
   scroll-reveal, and footer used by the "build system" pages:
     /build  ·  /quick-start  ·  /private-preview  ·  /latch
   Linked BEFORE each page's inline <style>, so any page-specific rule that
   needs to diverge simply lives inline and overrides this file. Page-specific
   layout (heroes, sections, cards, banners, toasts) stays in each page.
