This is a minor release, which improves keyboard shortcut handling.

This is a minor release that features a major performance bump for the embedded terminal emulator—up to 70% faster emulation in sequence parsing and virtual buffer manipulation. This leaves more CPU cycles available for smoother rendering :sparkles:

• terminal emulation improvements (RI, VPR)
• better text reflow upon terminal resize
• fixed big play button centering
• removed redundant CSS styles
