/* Dear Theo — a reading surface.
 *
 * Palette + Fraunces type inherited from the Quid Divinum brand (see qd
 * site/styles.css and AGENTS.md), tuned here for long-form reading: a narrow
 * measure, generous leading, quiet chrome. Light by default; a dark theme for
 * reading at night follows prefers-color-scheme.
