Frontend + UX/UI agents now carry a distilled design-taste bar in their team
prompts: the three dials (variance/motion/density) with dense-product-UI
defaults, plus typography/hierarchy, spacing/layout, motion, and AI-tells-to-
avoid rules, scoped to respect a project's existing design system rather than
override it. compose_prompt is unchanged (pure team/role prompt content).
developer.md gets a pointer whose heading deliberately does NOT start
'## Design bar', preserving the backend-dev negative test. New
tests/unit/agents/test_design_bar_layer.py (5 tests green).
Distilled from Leonxlnx/taste-skill (MIT).
