/* ستایش — چاپ و تبلیغات
   Design concept: a print house at night — foil-stamped gold on dark
   stock, ticket-like cards with a perforated notch, one deliberate red
   accent lifted from the brand mark's paint-splash. Single dark world
   by design (the letterpress/foil concept doesn't translate to a light
   ground), so no light-theme variant is defined. */
