feat: immerse the portfolio in a chromatic synthwave night

Carry rose, violet, coral, electric blue and cyan through the interface, road, terrain, signs and atmosphere. Add a Blender-authored paint edition and matching runtime fallback captures. Interpolate atmospheric color on a small sky lattice and enrich existing speed effects without another rendering pass.

Preserve approved copy, project media, metadata, navigation contracts and adaptive audio. Verified with typecheck, client/SSR builds, validated prerendering, artifact and transfer checks, responsive Chrome interaction, fallback checks and Intel-backed performance sampling.
