// Blowhorn docs skin: docs-only styling over Docsy and Bootstrap.
// Every value is a token from static/assets/brand/tokens.json (version 1).
// Light is the default; dark follows the OS. The marketing sheet (site.css,
// loaded after the Docsy bundle) owns the header, footer, type ramp, and
// element rules; this file owns the docs layout and Docsy components.
