docs: add tags to HF Space frontmatter for discoverability

docs: trim SUBMIT_NOW to fit lablab.ai form limits

docs+pptx: refresh all submission deliverables to match shipping pipeline

fix: load .env BEFORE importing signbridge — env-driven model name was always falling back

feat: Record sign uses Qwen3-VL native video_url (instead of frame sampling)

fix: drop broken Start/Stop label CSS — fixed 'Start' mid-recording + oversized post-record icons

ux: Record sign tab — wrap content in 3:2 columns to stop bottom-crop

ux: per-tab webcam constraints — Record sign tab gets 1280x720 (16:9)

ux: move 'Latest result' banner to right column as labeled gr.Markdown

chore: clean up stale CSS comment from gr.Markdown era

ux: switch latest status to gr.HTML with inline styles — guaranteed visible

ux: make per-click status banner highly visible (bordered, labeled)

ux: always show prediction + ✓added/✗dropped status, never silent

fix: cap webcam to 640x480 + delay JS auto-access — stop ClientDisconnect storm

feat: gTTS as primary TTS — Coqui XTTS-v2 was never installed on Space

fix: snapshot mode (drop streaming) — HF proxy can't sustain frame uploads

fix: webcam stream actually fires + JS auto-arms record toggle

fix: webcam capture — global cache, .change() event, drop share=True

fix: global frame-cache so click handler can actually see live frames

fix: read webcam directly on click instead of state-stashing

ux: streaming webcam + Take-image button — one-time permission grant

ux: auto-dismiss photo after recognition so next capture is one tap

ux: 2-button Snapshot tab (Take Photo auto-fires recognition; remove debug accordion)

fix: Clear button now resets webcam too + accurate help-text labels

fix: 4 Space runtime bugs found in line-by-line audit

fix: libgles2/libegl1 in Dockerfile + handle missing mp.solutions namespace

fix: pin starlette<0.41 — gradio 4.44.1 incompatible with new TemplateResponse signature

fix: share=True + SPACE_ID env to skip gradio's localhost-check pre-flight

docs: README — fine-tune narrative + hybrid pipeline diagram + model URLs

fix: set SYSTEM=spaces so gradio skips its localhost-check on HF Docker

fix: switch to Docker SDK so Python + launch are fully under our control

fix: remove python_version pin (was breaking gradio 4.44.1 launch on HF Spaces)

fix: app.py — let HF Spaces gradio runtime handle server_name/port

fix: pin python 3.10 (3.11 hit gradio localhost-check runtime error)

fix: requirements.txt — un-merge concatenated lines + drop server-only deps

fix: download MLP + MediaPipe weights from HF Hub instead of bundling

feat: MediaPipe+MLP landmark classifier — 90% ASL fingerspelling accuracy

fix: websockets<13 to satisfy gradio-client 1.3.0 dep range

fix: pillow<11.0 to satisfy gradio 4.44.1 dep range

fix: threading.Lock on LandmarkExtractor + composer prompt format match

feat(ui): Record-sign tab — multi-frame burst capture for full ASL words

feat(backend): /recognize accepts frames list + body-size cap

feat(vlm): add recognize_sign_from_frames for multi-image VLM input

feat(prompts): NVIDIA-pattern single-frame + multi-frame VLM prompts

perf: cache OpenAI-compatible client per (provider, model) tuple

refactor: extract closed vocabulary into signbridge.vocab module
