+## 2025-02-12 - Headless CLI Architecture Constraints
+**Learning:** This application is a headless CLI that exclusively outputs machine-parseable JSON envelopes to stdout for AI consumption. There is no human-readable UI, terminal text format, or web interface.
+**Action:** No visual, textual, or accessibility (a11y) UX enhancements can be applied. Stop execution without creating a PR when acting as the Palette persona in this repository.
