MC-4370

Elmar rejected the current MC Home visual/interaction quality: "the whole setup of the home page still doesn't look as professional as AionUI". He supplied AionUI mobile + desktop reference screenshots and asked Luci to run with this personally, not as another narrow worker polish loop. Reference evidence supplied this turn: - AionUI mobile/product refs: /home/lucienne/.hermes/image_cache/img_40aa192446da.jpg, img_22ad465076e8.jpg, img_f117a0dfe530.jpg, img_b835a1967c9d.jpg - AionUI desktop app refs: /home/lucienne/.hermes/image_cache/img_22ba9c1fe274.jpg, img_fb748ca2e6f2.jpg, img_3449d71ff812.jpg - Official site reference: https://aionui.com/ Current failures: 1. MC Home still feels like an internal/admin control page, not a polished AionUI-style AI workspace. 2. Composer is not premium/hero enough; provider/model controls are noisy and scattered. 3. Sessions rail still feels dense/failed-state-heavy and visually competes with the main composer. 4. Mobile/desktop regressions are being accepted from DOM tests rather than taste/visual proof. 5. User could not find a way to create a ticket from Home/Board; ticket creation must be obvious. Binding redesign direction: - Emulate AionUI desktop: quiet left rail, centered greeting, assistant/model segmented pill, large elevated composer, project/workspace chip, mode/model chip, compact suggested workflow/assistant cards. - Emulate AionUI mobile: one clean hero composer/card, horizontal assistant selector, structured chips, purple/dark primary CTA, generous whitespace; sessions behind Chats/sheet, not a cramped inline dashboard. - Controller is only a normal session/runtime context, never the dominant object. - Keep MC-4366 routing: active session primary opens Home/thread; ticket chip is secondary. - Add clear "Create ticket" / "New ticket" CTA on Home and Board; no hidden-only ticket creation. Acceptance: - Use official aionui.com and supplied images for visual comparison. - Implement a professional MC Home redesign pass directly in the main repo. - Add or restore obvious ticket creation CTA on Home and Board. - Regression tests cover create-ticket CTA presence plus Home IA copy/DOM expectations. - Capture desktop and 375px screenshots from live Tailscale route after deploy/reload. - Vision review against AionUI must explicitly PASS before DONE. - Run focused pytest with /usr/bin/python3, git diff --check, graphify update, commit+push. Expected check-in: within 60 minutes.
