/* Apex styles.
 *
 * Plain CSS, served as-is. No build step, no preprocessor, no bundler -- the
 * target machine has no Node.js, and a build step would be a hard blocker.
 *
 * Layout uses flexbox and grid; no framework. Custom properties for the
 * palette so a theme change is one block of edits.
