Current Work (newest first)

• [2026-02-20T11:10:51Z] follow-up: switched non-preserve token rendering to source-aligned inline segments; skip unmatched overlap tokens that caused duplicate phrase rendering; added regression test for two-line + duplicate-tail token payload.
• [2026-02-20T11:07:29Z] handoff: patched non-preserve token render path to flatten CR/LF into spaces (no <br> insertion); added regression test for formatter helper; build + renderer test pass.
• [2026-02-20T11:04:36Z] intent: investigate renderer regression reported when subtitleStyle.preserveLineBreaks=false; add targeted regression test + minimal fix.
• [2026-02-20T11:04:36Z] planned files: src/renderer/subtitle-render.ts, src/renderer/subtitle-render.test.ts, docs/subagents/*.
• [2026-02-20T11:04:36Z] assumptions: artifact originates in token render path for non-preserve mode, likely newline handling in token surfaces.
