What ships
Loxihart Signal uses the same four review dimensions for every effect. Renderer metadata reports implementation characteristics; visual quality is validated through render QA rather than invented numeric scores.
A proprietary visual contribution, not template soup.
Professional motion, hierarchy, physics, and typography.
The result must faithfully match the user’s requested intent.
