Directive 19: add Foundry VTT battlemap prompts (10 maps)

Browse Source 
Adds 10 Foundry VTT-spec playable battlemaps (BR19-VTT-01 through 10).
Distinct from the blueprint maps and evidence exhibits — these are the
maps PCs place tokens on during play.

FORMAT SPEC researched against Foundry VTT documentation:
- 100 pixels per grid square (Foundry default)
- Image dimensions clean multiples of grid count (no partial squares)
- Aspect ratios chosen for clean grid divisions (4:3, 7:5, 16:9, 9:5, 3:2, 2:1, 7:4)
- No baked grid lines (Foundry draws its own)
- No baked labels or text (added in Foundry as scene notes)
- No baked dynamic lights for indoors (Foundry's lighting layer handles)

STYLE DIRECTION: top-down orthographic painted floor plan, not blueprint.
Photorealistic-adjacent texture with Blade Runner colour grading. Sodium
amber + cyan + magenta neon noir, wet reflective surfaces, deep shadow
corners, atmospheric haze baked in. Cinematic painterly finish.

MAPS:
- VTT-01 Voss Penthouse (32x24, 3200x2400) — Act I opening crime scene
- VTT-02 Volkov's Clinic (24x18, 2400x1800) — Halden's introduction
- VTT-03 Pham's Marina Safehouse (28x20, 2800x2000) — Wren walks past
- VTT-04 Saltgrove Warehouse 7 (36x20, 3600x2000) — memorial / ledger
- VTT-05 Parking Structure (32x18, 3200x1800) — Sera ambush
- VTT-06 Sandoval 88th Floor (36x24, 3600x2400) — fundraiser
- VTT-07 Sandoval Roof (24x18, 2400x1800) — broadcast relay
- VTT-08 The Terrace (32x16, 3200x1600) — the climax stage
- VTT-09 Lin Ai's Noodle Bar (16x12, 1600x1200) — small conversation
- VTT-10 City Morgue (28x16, 2800x1600) — forensic scene

Shared style suffix locks orthographic projection, banishes grid lines
labels and tokens, sets the cinematic Blade Runner colour grade.

Per-scene Foundry setup notes included: scene config, walls/lights/sound
layer recommendations per location, token sizing, the replicant-magenta
trick (faint dim magenta point light follows Wren through scenes — players
feel her without seeing her), and iteration tips for fighting Midjourney's
tendency to drift toward 3/4 isometric instead of true overhead.

## Usage Notes for the GM
## FOUNDRY VTT BATTLEMAPS *(top-down playable maps for the virtual tabletop)*
These are the maps the PCs will actually move tokens on. Different format and intent from the blueprint plans above — the blueprints are *documents the GM hands the players*, these are *the physical space the scene happens in.*
### Format spec
- **Grid:** Foundry VTT default of **100 pixels per grid square** (1 square = 5 feet = one Medium token).
- **Image dimensions:** must be a clean multiple of 100 in both directions, no partial squares at the edges. Standard sizes used below: 2400×1800 (24×18 grid), 2800×2000 (28×20), 3200×1800 (32×18), 3600×2000 (36×20).
- **Aspect ratio:** 4:3 (24×18, 32×24) for box rooms, 16:9 (32×18) for wider scenes, 7:5 (28×20) for the warehouse. Width should be a multiple of 16 and height a multiple of 9 where 16:9 is used.
- **Output format:** ask Midjourney to render at maximum dimensions, then post-crop and resize in any image editor (Photoshop, Affinity, Photopea) to the exact target dimensions. **A clean crop to the spec size matters more than the original Midjourney resolution.**
- **No baked-in grid lines** — Foundry draws its own. The prompts below ask for no grid overlay.
- **No baked-in labels or text** — names get added in Foundry as scene notes.
- **No lighting baked-in for indoor scenes** — Foundry's dynamic lighting layer handles candle, lamp, and torch effects. Render ambient base lighting only.
### Style direction
Top-down orthographic floor plan view, **painted rather than illustrated**. Photorealistic-adjacent texture rendering with neon noir colour grading. Wet floor reflections, sodium amber and cyan rim lighting on architectural details, magenta accent where replicants have been present. **Blade Runner aesthetic translated into a playable surface** — high-contrast lighting baked into the floor and walls themselves, deep shadow in the corners, atmospheric haze. Asphalt-grime detail, rain-slick puddles, scattered debris where relevant. Cinematic colour grade.
### Shared style suffix *(append to every Foundry battlemap prompt below)*
```
top-down orthographic battlemap view direct overhead perspective no camera
tilt, photorealistic painted floor plan style for virtual tabletop play,
Blade Runner Los Angeles 2037 aesthetic, sodium amber neon noir colour
grading with cyan and magenta accent lights, high contrast deep shadows in
corners, atmospheric haze rendered in the air, wet reflective surfaces
where appropriate, asphalt and concrete texture detail, scattered urban
debris where appropriate, painterly cinematic finish, no grid lines, no
labels, no text, no characters or tokens, no UI elements, clean ambient
base lighting only no dramatic spot lights, edges of the map flush to the
frame no border or frame, slightly desaturated, gritty cyberpunk noir

### Foundry VTT Setup Notes
**Per-scene configuration in Foundry:**
1. **Upload the rendered map** to your `worlds/your-world/assets/maps/` folder.
2. **Create a Scene** in Foundry. Set the Background Image to your map file.
3. **Scene Dimensions:** Foundry will auto-detect from the image. Verify they match the grid count exactly (32×24 grid = 3200×2400px).
4. **Grid:** Square, 100 pixels, no offset. If your output is post-cropped slightly off, use the Grid Scaler module or adjust offset by hand.
5. **Walls layer:** Place walls along all internal partitions, doors as door-segments, windows as windows. This enables dynamic lighting and token vision.
6. **Lights layer:** Add point lights for each lamp / fluorescent / window visible in the map. Recommended for atmosphere:
- Voss penthouse: cool blue ambient through glass walls, warm amber from interior fixtures
- Volkov's clinic: a single cyan-flickering fluorescent above the procedure room
- Saltgrove warehouse: one hard white shaft through the broken roof
- Sandoval terrace: ambient amber from the city below, occasional magenta spinner pass
7. **Sound layer:** add an ambient track per scene. Recommended:
- Voss penthouse and Bradbury exteriors: rain on glass
- Volkov's clinic: autoclave hum + flickering fluorescent buzz
- Saltgrove warehouse: wind through corrugated steel, hard silence
- Sandoval fundraiser: string quartet polite chatter
- The terrace: heavy rain, wind, distant spinner pass
8. **Notes layer:** Place note pins on key features (the DIR-019 mirror, the kitchen bootprint, the body, the memorial beam) with one-line GM reminders.
**Token placement:**
- All grid squares assumed to be 5 feet
- A standard Medium token (200–400px square) fits one square
- For the Sandoval fundraiser, expect 6 PC tokens + Cortez + Wren + Halden + Sera + 6–8 named guest tokens at most — don't try to render 300 guest tokens, the painted dots on the map represent the crowd
**Lighting tip — replicant magenta:**
Add a faint magenta point light (radius 2 squares, dim) on a tile briefly when Wren passes through it. The players will feel her without seeing her. Same for Halden in the clinic scene (charcoal grey ambient with a single warm pen-light spot at the desk).
**Iteration guide:**
- Midjourney's top-down accuracy varies. Some prompts will need re-rolling 5–10 times to land orthographic projection.
- If a render comes back at a slight tilt (3/4 isometric), use `--style raw` + add `architectural plan view, no perspective, no foreshortening, pure overhead orthographic projection` at the end.
- For ambush / combat scenes, prioritise readability over atmosphere. The parking structure especially: players need to see cover positions clearly.
- **Print or display on the tablet** — these maps are designed to work both ways.
- **The blueprint maps are deliberately not playable battle grids** — they are scenery/orientation aids. Use the Acts screen of the GM app for the actual scene management.
