- window.prompt/alert are suppressed in Brave and installed PWAs, so the button appeared to do nothing. Replace with a proper modal (inline error, Enter/Escape, click-outside to close). - Mobile nav: sidebar was fully hidden (button unreachable); now sidebar shows by default and a back button toggles between list and thread. - Bump SW cache v1->v2 so the new shell actually ships past the cache.
