   COTRAX — shared base styles
   Extracted from the duplicated inline <style> blocks that
   previously existed on every page (index/about/blog/guides/
   tool/article/category/contact). Contains design tokens,
   reset, neon backdrop, base section/typography helpers,
   the shell (rail, header, nav, burger, mobile nav, buttons),
   footer, custom cursor/toast, and reduced-motion handling.
   Page-specific layout (hero variants, panels, grids, forms,
   FAQ, CTA bands, etc.) lives in assets/css/page-specific.css
   or, where genuinely unique, in a small inline block on the
   page itself.
