/* =============================================================================
 * Main stylesheet for NaNoWriMo Progress Tracker
 * =============================================================================
 *
 * CSS custom properties (variables) are injected at runtime by Hugo's
 * baseof.html template from the [params] section in hugo.toml.
 * This file ONLY consumes variables via var() — it does NOT define :root rules.
 * To change theme values, edit hugo.toml [params] — no JS changes needed.
