  • Improved synced lyrics romanization so Hangul-to-Latin conversion works more reliably across different module setups.
  • Fixed an issue where the lyric translation step could fail if the Hanja translation helper was exposed in a different format.

📝 Walkthrough

Walkthrough

romanizeHangul in the synced-lyrics renderer is updated to resolve the translate function from the hanja module via a typed interop shim (HanjaApi) that handles both named translate and default.translate export shapes, then passes the result to esHangulRomanize.

Changes

Korean Romanization Hanja Interop Fix

Layer / File(s)	Summary
HanjaApi interop and romanizeHangul update src/plugins/synced-lyrics/renderer/utils.tsx	Adds HanjaApi type and derives hanjaTranslate by checking for a named translate export or falling back to default.translate; updates romanizeHangul to call hanjaTranslate(line, 'SUBSTITUTION') before passing to esHangulRomanize.

Poem

🐰 A bunny hopped through module land,
Where exports hid from every hand.
Named or default? Both shall do!
hanjaTranslate now sees it through.
Korean lyrics sing once more~ 🎵
