更佳 YouTube 劇場模式

改善 YouTube 劇場模式，參考 Twitch.tv 的設計，增強影片與聊天室佈局，同時維持效能與相容性。另新增可選的、自製風格的浮動聊天室功能（僅限全螢幕模式），與 YouTube 原有的設計語言相融合。

v1.3.2 2025-01-06
Fixed a bug that caused the masthead width to not calculate when returning to the YouTube homepage.
v1.3.1 2025-01-04
Fixed an issue that caused the chat renderer width to be calculated incorrectly if the element is read too early while and only while using the "Open panel" button to uncollapse the chat box.
v1.3 2025-01-02
Script now makes the chat renderer extend fully to the top of the screen.
Script now scales the width of the youtube masthead dynamically to avoid covering the larger chat renderer.
Script now removes redundant borders from chat elements. YouTube stacks 2 extra borders on top of the pre-existing border created by the browser. This is particularly noticable when viewing in theater mode so that had to be fixed.

Note: v1.1 and v1.2 were never released
v1.0 2025-01-01
