/* tcgweb — design tokens first; every component below is written against
   roles, never raw hex, so light/dark and the theme toggle swap in one place.
   Light values live on bare :root. Dark is redefined under both the OS media
   query and an explicit [data-theme] stamp, so the toggle wins either way.

   Accent is #4a4099. The neutrals are biased slightly toward it rather than
   being pure grey, so the whole surface reads as one family.

   The four chart series are a validated categorical set — all six checks in
   the data-viz method pass in both modes (lightness band, chroma floor, CVD
   separation, normal-vision floor, contrast). Do not substitute a hue here
   without re-running the validator; the ordering is the CVD-safety mechanism,
   not a cosmetic choice.

   No webfont is loaded. The CSP is default-src 'self', and a private ledger
   should not phone a font CDN on every page view — so the stacks below resolve
   to SF Pro / SF Mono on the Mac this is read from, Segoe on Windows. */
