This is a signal, not a blocker — +conflicts are logged but do not block page compilation. + +### Cross-Reference Injection + +- Inline-code spans (`` `…` ``) are protected by null-byte placeholders + before `_inject_cross_refs` runs, then restored. This prevents concept + titles inside code from being rewritten. +- `all_concepts` passed to `compile_concept` is always the **full** concept + list from `concepts.yaml`, regardless of `--concept` filter.
