Current Work (newest first)

[2026-02-20T06:42:51Z] handoff: TASK-91 complete; added config flag subtitleStyle.preserveLineBreaks (default false), renderer token-linebreak alignment path, tests/docs/examples updated.
[2026-02-20T06:42:20Z] test: bun run build && node --test dist/config/config.test.js dist/renderer/subtitle-render.test.js pass (43/43); macOS helper compile falls back due sandboxed Swift cache write.
[2026-02-20T06:41:07Z] edit: added alignTokensToSourceText helper + preserve-line-break render path in src/renderer/subtitle-render.ts; state/config plumbing added.
[2026-02-20T06:39:34Z] test: added config parse/warn coverage + renderer helper newline-segment test.
[2026-02-20T06:35:38Z] intent: create backlog ticket; implement opt-in config flag default-off; keep current normalization default behavior.
[2026-02-20T06:35:38Z] progress: located normalization/render paths in src/core/services/tokenizer.ts and src/renderer/subtitle-render.ts.

request targets visible overlay rendering parity with MPV line breaks.
default behavior must remain whitespace-collapsed for tokenizer/texthooker consistency.
