 * Direction: editorial / paper. Warm cream backgrounds, single accent

 * No frosted glass, minimal shadows. Article body sits on its own paper
 * surface so it never reads as pure white-on-white or black-on-black.
 *
 * Loaded after main.css; only colors/typography/shadows/radii — no
 * positioning. Disable by removing the <link> in import.ejs to revert.
