-
-# Single-place functionality
-
-Where something can be done in one place and functionality remains absolutely the same, it must be done in that single place.
-
-Duplicated functionality is prohibited unless strictly required for the process.
-
-## Examples
-
-- UI state that belongs on a timeline clip (e.g. "Generated with" stale-prompt hint) lives on the clip only — not repeated on the player overlay, inspector, or toolbar.
-- Shared logic belongs in one module/function; views call it instead of re-implementing.
-- If two call sites need the same behavior, extract once and reuse — do not copy-paste with drift.
-
-## When duplication is allowed
-
-Only when the process genuinely requires it (e.g. server validation mirroring client hints for security, or ComfyUI node vs Movie Editor entry points that cannot share a runtime).
