* fix(ui): unbreak viz.html — OrbitControls importmap, WS URL, toast NPE (#760)
Three independent bugs were stacking to make ui/viz.html unusable from `main`:
1. Three.js r160 removed `examples/js/OrbitControls.js`, so the script-tag
load 404'd and `new THREE.OrbitControls(...)` threw. Switch to an
importmap that pulls the ES module build, then re-expose
`window.THREE` and `THREE.OrbitControls` so the existing component
modules (scene.js, body-model.js, …) keep working without a wider
refactor.
2. The WebSocket client was hardcoded to `ws://localhost:8000/ws/pose`,
but the sensing-server listens on `--ws-port` (8765 default, 3001 in
the Docker image) at `/ws/sensing`. Reuse the existing
`buildSensingWsUrl()` helper from `sensing.service.js` so port
pairings are handled centrally, and add a `?ws=…` query-string
override for non-standard setups. The websocket-client.js default is
also updated to derive from `window.location` instead of the dead
`:8000/ws/pose` literal.
3. `ToastManager.show()` called `this.container.appendChild(...)` even
when `init()` had never been called, throwing a TypeError that
killed the rest of page initialization. Auto-init the container
lazily on first show (patch from issue reporter).
Closes#760.

* fix(ui): single module script + mutable THREE — OrbitControls validated
Browser validation against the previous commit caught two stacked issues:
1. `import * as THREE from 'three'` returns a frozen Module Namespace
Object — assignment `THREE.OrbitControls = OrbitControls` silently
no-ops, so the global never gets the OrbitControls reference.
2. Two separate `<script type="module">` blocks (one installing the
THREE global, one consuming it via Scene) are independently
async-resolved. The second can finish dependency loading first and
call `new THREE.OrbitControls(...)` before the first script has run.
Fixed by spreading the namespace into a plain mutable object and merging
all initialization into a single module script with `await import()` for
component modules. Order is now strictly: import THREE → install
window.THREE → import components → run init().
Validated via agent-browser: page logs `[VIZ] Initialization complete`,
WebSocket targets the correct `ws://127.0.0.1:3001/ws/sensing` endpoint
(derived from buildSensingWsUrl), toast lazy-init confirmed via eval.

- Real-time performance monitor with FPS, memory, latency sparklines (draggable)
- Enhanced toast notification system with stacking, auto-dismiss, progress bars
- Dark/light theme toggle with localStorage persistence and system preference detection
- WCAG accessibility: skip-to-content link, ARIA roles/attributes on tabs and panels,
arrow key navigation in tab bar, focus-visible outlines
- ESLint config for UI directory with security and quality rules
* feat(ui): add command palette, activity log, data export, fullscreen mode, connection status
- Command palette (Ctrl+K / Cmd+K) with fuzzy search across tabs and actions

* feat(ui): add mobile hamburger nav, PWA support, and 40 unit tests
- Mobile hamburger navigation: slide-out drawer replacing tab bar on <768px,
swipe-to-close, animated hamburger icon, auto-sync with tab manager
- PWA manifest + service worker: installable dashboard, offline shell caching
(cache-first for static, network-first for API), auto-cleanup of old caches

syncs with TabManager, supports browser back/forward navigation
- Onboarding tour: interactive 6-step first-run walkthrough with spotlight
highlighting, step indicators, skip/back/next controls, localStorage persistence
- Idle detection: pauses health polling and reduces CSS animations after 3 min
of inactivity, resumes on user interaction, integrates with Page Visibility API
- Notification center: bell icon in header with unread badge, event history panel
with mark-read/clear, persists across page views via sessionStorage
* feat(ui): add i18n (EN/PL), screenshot tool, settings panel, reduced motion, uptime clock
- i18n: English/Polish translations with auto-detection, language selector
in header, data-i18n attributes on dashboard elements, localStorage persistence

compact layout mode, health polling toggle, clear data, reset onboarding
- Uptime clock: current time + session duration in header
- prefers-reduced-motion: system-level and manual toggle, disables all
animations and transitions for vestibular accessibility
- High contrast mode: WCAG AAA compliant colors for both light and dark themes
- Compact mode: condensed layout for dense information display
