- Removed 'e.bank||1' falsy trap (was converting bank 0 to 1) - Fixed TypeScript errors: cp guard, unused vars, path aliases - Added base: '/ui/' to vite config for correct asset paths - Bank persistence already implemented (localStorage pedal-footswitch-bank) - Rebuilt and deployed to src/web/ui-dist/
