Chat UX overhaul: sticky auto-scroll, copy/regenerate/continue actions, finish-marker handling, one-shot retry, localStorage persistence

Fix renderMdToFragment infinite loop on unmatched ** / backtick (streaming-partial freeze)

Strip debug logs; production-clean with @gradio/client@2.2.0 + break-on-complete

Upgrade @gradio/client 1.19.1 -> 2.2.0 (full rewrite, fixes iterator-not-closing hang)

Break for-await on status.stage=complete (verified via DevTools logs: 1.19.1 emits complete but never closes iterator)

Revert break-on-complete (was causing issues)

Break for-await on status.complete/error — fixes inflight-stuck Send disabled after turn 1

Bump @gradio/client 1.10.0 -> 1.19.1 — fixes sse_v3 diff streaming + HF token SSE auth

Surface stream errors/timeouts even when partial content arrived (no more silent truncation)

Add Model card link to topbar

Fix unresponsive chat after several turns

Drop NVIDIA SKU mentions, keep technical portability claim

Add lablab.ai hackathon submission attribution

Add 5-min research walkthrough video to About page

Add HF OAuth sign-in: forward visitor token to ZeroGPU backend

Tabbed UI (about=default tab, chat=second tab) + quota error handling

Restructure as single-page about-on-top + chat-below + CTA, loading status

Update askModel for new /chat schema (string in/out)

Replace C monogram with cyan-tinted Qwen logo (inlined as data URI)

Initial static frontend — calls athena129/cybersecqwen-demo via @gradio/client
