Reorganize docs into category folders and drop the retired head-review page

Group the top-level docs into docs/project, docs/design, docs/assets and
docs/process, each with its own README index. Delete the superseded
docs/screens/head-review page and sheets. Rewrite every markdown link,
absolute docs path and tool/test reference to the new locations, fix the
pre-existing broken anchors and remove the dead Joke Shop photo-board link.

+# Setup, Run and Test, and Controls
+
+## Setup
+
+1. Download Godot **4.7.2** (official build) and put `godot` on your PATH. The project, local tooling and CI use the same version; engine upgrades require import, headless, screenshot and Desktop HQ smoke checks before changing the baseline.
+2. Open or run the project from this directory.
+
+## Run and Test
+
+```bash
+# Open in the editor
+godot --editor --path .
+
+# Run the game
+godot --path .
+
+# Headless smoke boot (120 frames then exit)
+godot --headless --path . --quit-after 120
+
+# Run all unit tests headlessly (exit code 0 = pass)
+godot --headless --path . --script res://src/test/test_runner.gd
+
+# Check docs README coverage, tracked images and local links
+python3 tools/check_docs.py
+
+# Save a screenshot to user:// (windowed)
+godot --path . --script res://src/test/take_screenshot.gd
+
+# Visual-regression smoke: render the staged captures + prop gallery, then compare them
+./tools/check_screenshots.sh
+
+# Windowed control smoke: focus circle, action wheel, wheel cycling + right-click clear; saves PNGs, exits 1 on failure
+godot --path . --script res://src/test/smoke_focus_radial.gd
+
+# Session-shell smoke: menu → shift → pause → settings → menu (headless or windowed)
+godot --headless --path . --script res://src/test/smoke_session_shell.gd
+
+# End-to-end interaction smoke: inspection, radio, Help search, wand and review
+godot --headless --path . --script res://src/test/smoke_ui_flows.gd
+
+# PLAN-verb smoke: recognize, request reason, body camera, warning, blocking
+godot --headless --path . --script res://src/test/smoke_plan_verbs.gd
+
+# Prop-collision smoke (windowed): guard stops at a bench, guest routes around it
+godot --path . --script res://src/test/smoke_props.gd
+
+# NPC budget smoke: 24 full-rig avatars against the documented frame budget
+godot --headless --path . --script res://src/test/smoke_npc_budget.gd
+
+# Movement smoke (windowed): steps, precision walk, footsteps and landing
+godot --path . --script res://src/test/smoke_movement.gd
+
+# Crowd smoke: rubbernecking on aggression, panic clearing the entrance
+godot --headless --path . --script res://src/test/smoke_crowd.gd
+
+# Emergency smoke: unjustified call, investigation note, evacuation aftermath
+godot --headless --path . --script res://src/test/smoke_emergency.gd
+
+# Body-camera timeline smoke: review → timeline → step through → back to review
+godot --headless --path . --script res://src/test/smoke_timeline.gd
+
+# Audio smoke: crowd bed follows mood, radio open/close crackle
+godot --headless --path . --script res://src/test/smoke_audio.gd
+
+# Scenario-content smoke: wand refusal, celebrity crowd spike
+godot --headless --path . --script res://src/test/smoke_scenario_content.gd
+
+# Tutorial smoke (windowed): completion, replay and skip; isolated user data
+XDG_DATA_HOME=/tmp/gigline-tutorial godot --path . --fixed-fps 60 --script res://src/test/smoke_tutorial.gd -- --tutorial
+
+# Campaign/checkpoint smoke (windowed): resume, review continue, help; isolated data
+XDG_DATA_HOME=/tmp/gigline-campaign godot --path . --fixed-fps 60 --script res://src/test/smoke_campaign.gd
+```
+
+The unit test runner is the project's own lightweight harness (no editor plugin required) so CI can run it without the editor.
+
+## Save Data
+
+The game writes four JSON files in Godot's `user://` directory:
+
+| Platform | Location |
+| --- | --- |
+| Linux | `~/.local/share/godot/app_userdata/Gig Line/` |
+| Windows | `%APPDATA%\Godot\app_userdata\Gig Line\` |
+| macOS | `~/Library/Application Support/Godot/app_userdata/Gig Line/` |
+
+Files: `settings.json`, `campaign.json`, `shift_results.json` and the versioned
+`shift_state.json` checkpoint. The schema, migration/default-filling rules,
+atomic-write behavior and checkpoint contents are in
+[`architecture.md#persistence-and-save-contract`](../project/architecture.md#persistence-and-save-contract).
+
+For a clean first launch, delete the four files (or the whole `Gig Line` user
+directory). Settings' **Reset campaign** clears campaign progress separately.
+To back up or move a profile, copy the files while the game is closed; restore
+them to roll back. Shift history is diagnostic and not required to resume.
+
+## Controls
+
+Keyboard and mouse are the default; a gamepad works without configuration (left stick moves,
+right stick looks, A opens/confirms the wheel, B cancels, X inspects, Y calls the radio, LB walks
+slowly, RB uses the wand). Keys and pad buttons can be rebound in Settings, and the remaps persist
+in `user://settings.json`. The HUD legend switches to gamepad hints when a pad event arrives.
+
+| Input | Action |
+| --- | --- |
+| W/A/S/D + mouse | Move and look |
+| Space / left click | Action wheel for the focused person (Stop, Look, Point, No, Ask, Inspect, Wand, Warn, Block, Reason, Recognize, Radio) |
+| A / D or ←/→ | Step through the action wheel (while it is open) |
+| Space / left click | Confirm the highlighted action (while the wheel is open) |
+| Esc / right click | Close the top panel; Esc with nothing open pauses the shift (Esc again resumes) |
+| ← / → or ↑ / ↓ | Navigate the venue menu and the pause / settings panels |
+| Enter | Start the highlighted venue from the menu, or confirm in a panel |
+| 1 / 2 / 3 | Quick gestures without the wheel: raise hand, point, head shake (Level 1) |
+| Q | Polite direction (Level 1) |
+| 4 | Formal warning (Level 2) |
+| 5 | Blocking and positioning (Level 3) |
+| 6 | Security assistance radio (Level 4) |
+| R | Emergency radio, hold on-screen button ~1.6s (Level 5) |
+| E | Inspect access artifacts / close inspection |
+| C | Handheld wand screening (wand venues only) |
+| A / D | Allow / deny entry during inspection or wand check |
+| V | Cycle venue (debug shortcut; restart via V restarts the current shift) |
+| Tab / mouse wheel ↓ / ↑ | Cycle the target among nearby NPCs, nearest first (aim-free; the target stays selected) |
+| Right click (nothing open) | Clear the focused person and return to aim-based focus |
+| Shift (hold) | Precision walk at roughly half speed for close work at the door |
+| G | Toggle flashlight (widens NPC perception at night) |
+| B | Toggle the body camera; a formal warning switches it on automatically |
+| L | Lock / unlock the restricted door (thwarts forced entry) |
+| F | Toggle debug overlay |
