/* ============================================================
 * single.php — Single Article CSS
 * Φορτώνεται ΜΕΤΑ το golab-design-system.css (βλ. golab_enqueue_page_assets)
 *
 * ΣΗΜΑΝΤΙΚΟ: το functions.php αφαιρεί το wp-block-library CSS από όλο το site
 * (golab_remove_block_css), άρα τα block του Gutenberg (εικόνες, αλλαγή
 * στοίχισης, gallery, embeds, quote) ΔΕΝ έχουν στυλ από το WordPress.
 * Όλα όσα χρειάζονται ορίζονται εδώ, μέσα στο .golab-single__content.
 *
 * Τα selectors έχουν ".golab-single" μπροστά ώστε να υπερισχύουν του
 * style.css του child theme (που φορτώνει αργότερα, priority 999).
 * Τα fallback στα var() ισχύουν μόνο αν λείπει η μεταβλητή από το design system.
