/*
 * Imprint Tech Blog — "Direction C — Stacked Statement" redesign.
 *
 * Recreates the Imprint Design System tokens and type ramp from the design
 * handoff. The production design system (github.com/Imprint-Tech/imprint-ui)
 * is a React/TS library and is not consumable from this Hugo site, so the
 * tokens it exports are reproduced here verbatim. Values are pulled from the
 * handoff README (colors_and_type.css). Universal Sans is not licensed for
 * this static site, so we use Inter — the design's named fallback.
 *
 * This sheet loads AFTER the theme's Tachyons bundle (see head-additions.html)
 * so it layers on top of the base utility classes.
