/*
 * site.css — layout for deepwrench.com.
 *
 * Everything here traces to one of two sources: a token in tokens.css, or a
 * value in the Claude Design handoff (design/handoff/DeepWrench Site.dc.html),
 * which carried every style as an inline attribute. The port moved each of
 * those into a class below, value for value, because the site's CSP has no
 * 'unsafe-inline' — an inline style attribute would not render on Cloudflare.
 *
 * Modernist rules this file obeys: zero corner radius (there is none anywhere),
 * no shadows, no gradients, and no second accent. Separation is the 2px
 * --rule-strong between sections and the 1px --rule-hair between cells.
 *
 * The site ships no JavaScript. There is no theme toggle: both palettes come
 * from tokens.css under prefers-color-scheme.
