   OUR LOVE STORY — style.css
   Direction (from unslop): intimate, unhurried, tender.
   World: a private film and its contact sheet — title card, letterbox, a red thread.
   One warm-black ramp, one muted red accent, gold only for Maryam's achievements.
   Spacing on a 4px grid. One easing curve. No glow, no hue gradients.
   Persian type: never add letter-spacing; line-heights are taller than Latin.
