 * POLYROB Design System — Primitives
 * Framework-agnostic structural + component CSS, extracted from the webview
 * (webview/static/css/style.css + components.css) so the portal, docs, and
 * skill catalog render the SAME terminal aesthetic as the running product.
 *
 * RULE (the token contract): every value here is composed from variables.css.
 * No raw hex colors, no nonzero border-radius, no new font stack. If you need
 * a new value, add a token to variables.css — never inline it here.
 *
 * Load order:  variables.css  ->  primitives.css  ->  <surface>.css
