/*
  chessKish — shared stylesheet for the statically served pages.

  One small file instead of inline <style> blocks so the landing pages stay
  readable and the CSS is fetched once and cached.

  The palette is copied from the application itself, not invented here:
  --paper / --accent are the tokens in lib/src/view/home/home_dashboard.dart and
  lib/src/widgets/web_scaffold.dart (0xFFF6F2EA and 0xFF9A6B3F). Keeping the
  static pages on the same tokens means a visitor who clicks through to the app
  sees one continuous product rather than a marketing site bolted onto it.
