+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Color subtitle tokens that match entries from the SubMiner character dictionary, with a configurable default color and a config toggle that disables both rendering and name-match detection work.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Tokens matched from the SubMiner character dictionary receive dedicated renderer styling.
+- [x] #2 `subtitleStyle.nameMatchEnabled` disables name-match detection work when false.
+- [x] #3 `subtitleStyle.nameMatchColor` overrides the default `#f5bde6`.
+- [x] #4 Regression coverage verifies config parsing, tokenizer propagation, scanner gating, and renderer class/CSS behavior.
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Added configurable character-name token highlighting with default color `#f5bde6` and config gate `subtitleStyle.nameMatchEnabled`. When enabled, left-to-right Yomitan scanning tags tokens whose winning dictionary entry comes from the SubMiner character dictionary; when disabled, the tokenizer skips that metadata work and the renderer suppresses name-match styling. Added focused regression tests for config parsing, main-deps wiring, Yomitan scan gating, token propagation, renderer classes, and CSS behavior.
