/* DIRECTION: editorial print, light (warm off-white paper + charcoal ink). Named precedent: brand brief palette,
   Stripe/Linear-style restraint on a printed-brochure grid; sibling cvsolve site is dark, so this one is deliberately light.
   ONE MEMORABLE THING: "יום אחד בחנות" — a two-sided day timeline (לפני | אחרי) sharing one hour spine, plus the hero headline
   where "מתקינים ועוזבים" is struck through and "מטמיעים" carries a single lime marker.
   TYPE: Rubik 700/400 (he) + IBM Plex Mono (indices, chips). ACCENT: olive #4c6f0a for text/rules (5:1 on paper),
   lime #C6F24E only as marker/CTA fill. LAYOUT PRIMITIVE: asymmetric 2-col with hanging mono index. MOTION: mathematical. */
