LEN-105: Privacy & Local AI + Themes pages; expand scan/events/grocery/Ask-Dot with fresh shots
UI polish refresh — PR #271 (web) + PR #282 (mobile) Web shots re-captured against the polished UI; Flutter captures refreshed for renamed tabs (Home/People, selected-label-only nav), floating-label forms, aisle-grouped grocery lists, allergen badges, labeled Adjust/Snooze actions, and Ask Dot prompt chips. New mobile shots: meal plans, notification settings, wine cellar. Prose updated for renamed tabs, People-tab settings gear, "usually buys" captions, on-first-visit camera permission, and shipped features removed from the roadmap list.
Refresh Ask Dot screenshots (web + mobile) and on-device model docs - assistant.png / assistant-answer.png: recaptured from lena2shots with the merged local-AI UI (engine badge 'Via server', tool-call footer) - mobile-assistant.png: real Pixel 10 Pro emulator exchange showing the opt-in card, tool lookup trace, and engine label - mobile-assistant-optin.png: new on-device model download opt-in card - Mobile-Ask-Dot.md: embed the opt-in shot under the on-device section
Split Mobile-App into per-feature pages (dashboard, grocery, scanning, pantry, events, household, recipes, Ask Dot)
