 ## Acceptance Criteria
 <!-- AC:BEGIN -->
-- [ ] #1 Add an opt-in setting/feature flag so JLPT tagging is disabled by default and can be enabled per user/session as requested.
-- [ ] #2 Bundle the existing JLPT Yomitan extension package/data into the project so lookups can be performed offline from local files.
-- [ ] #3 Implement token-level dictionary lookup against the bundled JLPT dictionary file to determine presence and JLPT level for words in subtitle lines.
-- [ ] #4 Render a colored underline under each token determined to have a JLPT level; the underline must match token width/length and not affect layout or disrupt line rendering.
-- [ ] #5 Assign different underline colors per JLPT level (at minimum N5/N4/N3/N2/N1) with a stable mapping documented in task notes.
-- [ ] #6 Handle unknown/no-match tokens as non-tagged while preserving existing subtitle styling and interaction behavior.
-- [ ] #7 When disabled, no JLPT lookups are performed and subtitles render exactly as current behavior.
