/* Concept F · "Two Streams" — built with build-awwwards-quality-sites (mengto collection)
 * Compatible web-design skill named: garden/web-design-engineer (this project's recorded lead workflow)
 * Visual thesis: two things becoming one. The hero shader, the section rhythm and the
 *   twelve-month scrub all enact convergence. Dark-first — the only concept that inverts
 *   the brand, so it reads as a different proposition rather than a restyle.
 * Hero focal asset: fullscreen WebGL fragment shader, two flowing bands merging into one line.
 * Three.js decision: NOT USED. One fullscreen quad does not justify ~600KB. Raw WebGL
 *   fragment shader instead (~4KB, one responsibility). Reported per skill step 7.
 * Smooth scroll: Lenis, sole engine. Locomotive evaluated and rejected (heavier, and its
 *   transform-based scrolling fights the pinned ScrollTrigger sequence).
 * Motion: GSAP + ScrollTrigger, self-hosted. Reduced motion renders final states immediately.
 * Assets: no photography or avatars — no licensed source is reachable from this environment,
 *   so they are honestly omitted rather than faked. No logo wall (no real proof exists).
 *   Solar icons via the offline @iconify-json/solar package. Client's own logo preserved.
 *   No model-authored illustration; data graphics and the shader only.
 * Colour: brand-locked, inverted. Verified — cream/ground 15.67, muted/ground 7.73,
 *   gold/ground 6.81, teal/ground 3.12 (UI only, never text), line/ground 1.76 (hairline only).
