Why change subtitle case?

Broadcast rips and older fansubs often ship as shouty ALL-CAPS or inconsistent mixed case. A single pass re-cases every line — pick Title Case for clean reading, or UPPERCASE if your player renders it better.

It's a pure text transform: timings and structure are untouched, and the file never leaves your browser.
