 Completion checks: swift build and swift test pass; no dangling HEX symbol links or references remain. Supported hex syntax and Config appearance are unchanged. Explain the kept/removed API choice in the change description so it can be reviewed separately from strict input validation.
 
 Design constraint: Follow README.md: keep source-based configuration, no dependencies or plugin framework, and use the smallest readable change that makes the existing behavior reliable. This is a suggestion for individual review, not a deadline. Findings were recorded on 2026-10-14; re-check the current code before implementing.

+## Completion
+
+Reference review found no callers of the HEX wrapper, Color.init(hex:), or
+Color.Resolved.hex in Sources, Tests, examples, or published patches. Removed
+these unused conversions to keep source customization focused on the existing
+Color.hex(String) helper. Moved that helper to Models/Color+Hex.swift and updated
+Config and DocC references. The published background-blur patch uses only the
+retained .hex(String) helper and needs no change.
+
+This is API simplification, separate from strict input validation: the parser
+body is byte-for-byte unchanged, as are configured foreground, background, and
+highlight values. Supported syntax and existing malformed-input behavior remain
+unchanged. Users with private customizations that call the removed helpers can
+use Color.hex(code) for forward conversion or keep their own conversion helpers.
+
+Validation: swift build succeeded; swift test passed all four existing tests;
+make -C Sources/bar/bar.docc build completed without warnings or unresolved
+links; reference search found no remaining removed-API references in Sources,
+Tests, patches, or README; git diff --check passed.
