/* ==========================================================================
   Manual Barn — consolidated stylesheet (W2 quality-pass rebuild)
   One file, mobile-first, custom properties, responsive at 360/768/1200.
   Replaces the per-page inline <style> blocks that were duplicated across
   the whole site. No visual language change beyond formalizing the
   existing palette/type into tokens and adding the new chrome components
   named in the build plan (topbar, hub-hero, stat-chip, table scroll,
   noscript fallback, skip link). Body copy and data values are untouched
   by this file — CSS only ever targets layout, colour, spacing and type.
