## Current Work (newest first)

- [2026-02-20T05:44:45Z] handoff: completed TASK-89; default subtitle background updated to `rgb(30, 32, 48, 0.88)` across config defaults, docs examples, and renderer fallback CSS.
- [2026-02-20T05:44:45Z] test: `bun test src/config/config.test.ts` pass (33/33) after adding regression assertion for `config.subtitleStyle.backgroundColor`.
