- rename v2.0 → EurKEY Next across all files, scripts, workflows, website
- rename bundle EurKey-macOS → EurKEY-macOS
- add §/± to ¬ dead key (¬+s → §, ¬+S → ±) for ANSI keyboard compatibility
- normalize Caps Lock = Shift across all four layouts, remove custom Caps bindings
- fix v1.4: revert accidental Caps/ẞ changes, correct changelog to super/subscript swap
- update README: remove duplicate v1.2–v1.4 changelog, reorder versions (Next first)
- update website: ISO+ANSI feature card, EurKEY Next branding, consistent version order
