/* AL MAHA v3 — style layer «روح v2» (?style=v2, <html data-style="v2">, set in <head> before the first paint).
   What it takes from ChatGPT's v2 (analysis-v2/v2-extract.json): the warm yellow-neutral surfaces, one flat band per
   chapter, copper on the night chapter, the tighter section rhythm (≈105 / 95 px desktop, 65 / 61 px phones) and the
   approach as tabs 01-04 with a big numeral. What it keeps from v3: the brand reds (#EB070D / #8E1028), the type sizes,
   Arabic never tracked, the seams, the vector oryx, the markup. Default (no parameter) stays the v3 style. */
