/* S1 by SHARQ — waitlist.
   Black ground, warm white type. Two voices: Archivo (Latin) and Noto Kufi (Arabic), because the
   product itself decides in Arabic. The ember palette lives only in the 3D sun and the field's focus
   line — the sun's light touching whatever you are filling in. No page gradients, no borrowed effects.
   v6 (2 Nov 2026): redesign — bilingual type, a horizon, flat fields. */
