   --------------------------------------------------------------------------
   Single stylesheet for the entire site (reuse-A).
   No inline styles, no framework, no third-party asset.

   Visual direction: premium automotive — a carbon-dark structural base,
   paper-light content surfaces, precision grid alignment, sharp geometry,
   a single warm "signal" accent used sparingly, and motion that feels
   mechanical rather than bouncy. All tokens below are original to this
   project; no external brand palette is reproduced.
