Give live feedback that something is happening the moment a session starts
processing: the red stop dot in the composer beats with a soft heartbeat + halo
while the harness is actively working (running — not waiting at a gate or
finalized), and settles the instant the model hands control back to the reviewer
or the session ends. Ring/scale only (no layout properties animated); honors
prefers-reduced-motion.

New session now refuses to spawn a Pi runtime that would only die in bootstrap
retrieval when the DWH/vector host is unreachable (e.g. a dropped VPN). Before
`session new`, POST /sessions probes the DWH via `tht db ping`; if it is down it
returns 503 {code:"dwh_unreachable"} with a clear message and creates nothing.
- Gated behind the THT_DWH_PRECHECK flag (default off), enabled only by the local
dev launcher (run-stack.sh) — containers/CI never pay the probe, and existing
tests that don't set it are unaffected.
- ThtRunner.dbPing() runs `tht db ping` with a 10s timeout (run() gains an optional
timeout that SIGKILLs a hung child).
- Frontend: apiFetch throws a typed ApiError (status + parsed payload); the new-
session composer shows the specific alert on `dwh_unreachable` instead of the
generic retry hint, keeping the question for retry.
Verified live on an isolated backend (precheck on + broken DWH host → 503
dwh_unreachable, no session created) and via unit tests (backend 228, frontend 308).

Fix six GUI defects, verified live against the real stack:
- NavSessions: mark the in-progress (active) session in yellow (warning
token) — both its status dot and its row background.
- SteerInput: the composer is now an auto-growing textarea that wraps and
grows vertically (caps at 160px, then scrolls); Enter sends, Shift+Enter
inserts a newline.
- WorkflowBar: show a synthetic title of the current phase under the 8 dots
from static EN/IT strings (no LLM); English is displayed to match the chrome.
- CentralStatus: reformat the 5-line system-message tail as a structured,
monospace list with per-line markers and an emphasized last line.
- AppShell + CentralStatus: move the left Model-activity panel toggle off the
working spinner (now a pure status indicator) onto a dedicated arrow button
(→ opens, ← closes).
- gate: rename the phase-confirm button "Conferma e prosegui" → "Salva e
procedi" (builders.js + its L1 test).

- Remove the microphone icon from the composer footer
- Left: workspace selector in its place
- Right: model + thinking-level selectors (persist via PUT /settings) next to
the context-usage gauge
- Delete the Settings dialog (form + button); only "New session" remains

- Center ThothII logo + tagline; break "Human In The Loop" onto a second line
- Rename "New question" → "New session"; the button now clears the screen and
focuses the sticky bottom composer instead of opening a dialog
- Composer is always rendered and pinned at the bottom; typing the first
message there creates the session (no modal)
- Add inline stop control (square + inner circle) that interrupts and saves
the session via /close
- Always-present send affordance (CornerDownLeft ↵) on the right of the box
- Status footer under the box: mic (inert), model name, thinking level, and a
context-usage gauge (placeholder)
- Brand-tinted spinner beside the logo while the harness/backend holds the
ball; hidden once a widget needs human input

The interface is now fully English regardless of the chat language (session
titles stay in whatever language the user typed). Changed the right-rail
subtitle to 'Datamart Builder with Human In The Loop'. Translated all chrome:
new-question/settings dialogs, workflow phase strip (F1-F8), session rail,
steer input, widgets (select/multiselect/freetext/fallback/reserved controls)
and viewers (SQL, results, schema linking). Test matchers updated in lockstep.

Adopt the portal's design language so the app embeds seamlessly into its
header/sidebar chrome later:
- Token layer rewritten as raw OKLCH triplets (the previous oklch()-wrapped
vars produced invalid colors; the UI was effectively unstyled). Values mirror
GSD: Manrope + Fraunces fonts, #cb333b red brand, warm off-white surfaces,
pill buttons, brand focus rings. Dark tokens follow .dark or the portal's
[data-bs-theme=dark].
- Layout: no left sidebar, no header (the portal supplies them). Conversation
column flush-left with a slim F1-F8 phase strip; session rail moved to the
RIGHT, mirroring the portal's left sidebar (red section label, red-tint active
item). Editorial empty state.
- Transcript component now actually renders the streamed assistant turns (the
store accumulated them but nothing displayed them). Toaster mounted for errors
(matchMedia polyfill added to the jsdom test setup).

- NavSessions: left nav listing sessions via listSessions (TanStack Query),
clicking resumes via resumeSession and sets active; active item highlighted
- NewSessionDialog: ShadCn dialog with question textarea, workspace native
select (from listWorkspaces), graceful model field (dropdown when models
list is non-empty, free-text input when empty per §9 degradation),
optional thinking/provider fields; try/catch surfaces errors inline
- SteerInput: text input + button POSTs to postSteer, clears on send,
supports Enter key; only shown when a session is active
- WorkflowBar: renders 8 phases (F1..F8) with data-active highlighting
driven by useSessionStore.currentPhase (new store field + setPhase action)
- AppShell: wires all four components; right artifact sidebar now collapsible
via a toggle button (useState sidebarOpen); replaces old "Nuova domanda"
button with NewSessionDialog trigger
- f1-loop.test: updated to drive through the new dialog flow (open → fill
question → submit → wait for SSE → respond)
