   Parments — base.css
   The single shared stylesheet loaded by templates/base.html on every page.
   1) Base layout: reset, floating navigation, messages, footer, mobile rules
      (moved verbatim from the former inline <style> in base.html)
   2) Design system: tokens, global safety nets, touch targets, ui-* components
   Page-specific styles stay in each template's {% block extra_css %}.
