- Move traffic-light buttons to the LEFT side of titlebars (close/minimize/maximize)
in macOS order, using fixed left-pad positions instead of right-edge offsets
- Adopt macOS dark-mode color palette: #3C3C3C active titlebar, #2C2C2C inactive,
traffic-light colors #FF5F57/#FEBC2E/#28C840, near-black #1C1C1C desktop
- Center window title text in the titlebar (macOS style), clamped to avoid
overlapping the left button cluster
- Thin 1px window borders replacing the original 3px beveled border
- macOS blue (#4A90D9) selection highlight in the context menu
- Neutral dark context menu (#2C2C2C) with subtle separators and text indent
- Update README to document the ElemetryOS macOS fork identity and design changes
