About this conversion
SSA (v4) and ASS (v4+) are close cousins, but ASS adds the richer styling, positioning (`\pos`) and effects that current tools like Aegisub expect. Converting SSA to ASS upgrades the header to `[V4+ Styles]` and normalises the `Dialogue` lines so the file opens cleanly in modern editors without legacy-format warnings.
