Add the first-shift tutorial design and state machine

Write the eight-beat tutorial sheet, its safe visitor script, persistence and
replay rules. Add a deterministic, skippable/restartable Tutorial RefCounted
state machine with headless tests. UI/GameManager wiring remains the next task.
Headless 235/235, Python 94/94.

 - Visual alignment: start/venue menu, pause, settings, shift review, radio, wand, inspection, timeline, HUD target chip/escalation bar, and radial menu now use or match their AI references in `assets/images/ui/`. The runtime art loader (`src/game/ui/art.gd`) falls back cleanly when a file is missing.
 - Realism adoption (post-v0.6.0): v2 per-phase skylines and surface tiles with normal maps, retuned sun/exposure/fog, wet asphalt, denser foliage, a visible additive flashlight beam, and refreshed staging captures. `tools/check_screenshots.sh` is the repeatable capture/compare gate; judge is clean of `diff` verdicts.
 - Input/reliability fixes: selecting a venue now releases the start-menu input lock and recaptures the mouse; the body-camera overlay no longer covers the shift status.
+- Tutorial foundation (0.8.0 work): the eight-beat first-shift design and a deterministic, skippable/restartable `Tutorial` state machine exist; the in-game prompt/visitor wiring is the next step.
 - Vision judge (v0.7.2): discovers the cheapest current OpenRouter image+JSON model, reports the model/fallbacks used, and clears the full screen-design judge (13/13 match, 0 diff).
 - Desktop HQ (v0.7.1): optional Forward+ Windows/Linux zip with volumetric fog, SDFGI and a volumetric flashlight; the default Compatibility/Web builds and headless tests gate the effect off. A/B captures are generated locally under `docs/screens/realism/` (gitignored).
 - Venue geometry (v0.7.0): the Joke Shop now builds as a narrow brick alley with a warm wall lantern, shutters, dumpster/AC clutter and no skyline; the TV Studio builds a stone facade, bulb canopy, glossy black car and barrier line. `WorldBuilder.VENUE_SPECS` drives facade/street/nav dimensions, and `GameManager` rebuilds only the world container when the venue changes.

+# First-shift tutorial
+
+Status: planned for v0.8.0. The tutorial teaches the real controls and the real
+inspection/wheel/radio panels; it is not a fake UI or a separate combat mode.
+
+## Rules
+
+- One short, safe, compliant visitor. No emergency, threat, crowd panic or random
+  event can interrupt the tutorial.
+- Prompts advance on the performed action, not on a timer. The player can keep
+  moving/looking while a prompt is visible.
+- The tutorial is skippable at any point. Completion and skip are both persisted
+  separately; a skipped tutorial can be replayed from Help/Settings.
+- The tutorial state machine is independent of the shift FSM. It observes the
+  same actions as normal play and must be deterministic for tests.
+
+## Beat sheet
+
+| # | Beat | Prompt | Advances when | Notes |
+| --- | --- | --- | --- | --- |
+| 1 | Arrive | "Walk forward and look around. The entrance is behind you." | The guard has moved at least 1 m and looked away/returned | Start at the normal guard post, facing the street. |
+| 2 | Focus | "Look at the visitor. Press Tab or the mouse wheel to cycle targets." | A target is acquired and explicitly cycled | The visitor waits at the foot of the steps; no other guest is required. |
+| 3 | Wheel | "Open the action wheel with Space or left click." | The radial wheel opens on the visitor | The wheel is the real de-escalation-first wheel. |
+| 4 | Inspect | "Choose Inspect and read the access evidence." | The inspection panel is opened and the policy result is visible | Use a valid wristband so the tutorial can teach both evidence and a safe admit/deny decision. |
+| 5 | Direction | "Close the panel and give a polite direction." | A Level 1 polite-direction action is applied | The visitor complies; there is no escalation requirement. |
+| 6 | Warning | "Give a formal warning if the visitor persists. It arms the body camera." | A Level 2 warning is applied or the body camera is switched on | Show the REC overlay and the escalation cue. |
+| 7 | Radio | "Open the assistance radio and submit a short report." | The assistance report is submitted successfully | A non-emergency assistance call; no responder is required to resolve the tutorial. |
+| 8 | Review | "Finish the shift and review what happened." | The shift review opens | The tutorial ends; the real review remains available for inspection. |
+
+## Visitor script
+
+- Display name: `Visitor`.
+- Intent: `enter` (approaches the door, then waits for interaction).
+- Access: valid wristband evidence; the policy result should be unambiguous.
+- Behavior: compliant at every escalation level; never becomes a threat, never
+  joins a crowd and never triggers an emergency.
+- Failure handling: if the player denies admission incorrectly, the tutorial
+  explains the evidence but does not fail the run; the visitor remains safe and
+  the review records the decision.
+
+## Persistence and replay
+
+Settings gain `tutorial_completed` and `tutorial_skipped`. A first launch starts
+the tutorial after venue selection. Skipping sets `tutorial_skipped`; Settings/
+Help offers "Replay tutorial", which clears both flags for the next shift.
