/* style.css — wspólny arkusz bloga drukarniapro.pl
   Źródło designu: repo drukarniapro-v2, app/globals.css (@theme, "Paper / Ink 2026").
   Blog jest SPÓJNY ze stroną, nie identyczny: bierzemy paletę, Inter, styl przycisków,
   promień zaokrągleń i jasny nav; zostawiamy własny, węższy layout czytelniczy.
   Plik nie przechodzi przez .format() w Pythonie — klamry CSS są bezpieczne.
   Wersjonowanie cache: szablony linkują /blog/style.css?v={style_ver}, gdzie style_ver
   to hash treści tego pliku liczony w site_builder.build(). */
