 * home.css — Homepage-only stylesheet
 * Theme : 2025
 * Author: Naser Shahsavar (iNaser)
 *
 * Design direction: editorial minimalism with a strong typographic voice.
 * Monochrome base, a single warm accent, generous whitespace, sharp details.
 * No utility bloat — every rule has a purpose.
 *
 * Load order: Vazirmatn font → home.css (both enqueued via wp_enqueue_scripts).
