Four famous food cities rendered in a multi-scale poster grid

2x2 grid, 16:9, do this for 4 famous foodie cities: // ═══ SCALE Λ (Lambda): 4 levels, each with own physics ═══

Λ_0 (MACRO, ~1m): "GALLERY CONTEXT"
  physics: {
    geometry: "flat_wall, single_object, centered"
    light: "ambient_gallery_spot, soft, from_above"
    detail: "poster is ONE shape. No internal detail visible."
    color: "white_wall + dark_frame_rectangle"
    rule: "poster reads as a SINGLE GESTALT object"
  }
  ↓ flow (zoom in)

Λ_1 (MESO, ~50cm): "POSTER LAYOUT"
  physics: {
    geometry: "3 horizontal zones, Swiss grid, construction lines"
    light: "flat, even, printed_ink (no 3D lighting yet)"
    detail: "typography readable, grid visible, zones distinct"
    color: "{{PALETTE}}, # 1a3a6b, #111, # F5F0E8"
    rule: "reads as GRAPHIC DESIGN. Flat. Intellectual."
    elements: [header_grid, footer_diagram, construction_overlay]
  }
  ↓ flow (zoom into center zone)

Λ_2 (MICRO, ~15cm): "3D FOOD TYPOGRAPHY"
  physics: {
    geometry: "volumetric, photoreal, casts_shadow_on_Λ_1"
    light: "studio_3point, specular, SSS, caustics_in_glass"
    detail: "rice_grains, fish_fiber, batter_crunch, nori_wrinkle"
    color: "full_spectrum, ingredient-accurate"
    rule: "reads as PHOTOGRAPHY. Tactile. Hungry."
    elements: [{{LETTER_MAP}} as 3D objects]
    INTERACTION: "3D objects from Λ_2 cast shadows INTO Λ_1"
    // this is the SCALE BREAK: photoreal objects on flat poster
  }
  ↓ flow (zoom onto a letter)

Λ_3 (NANO, ~2cm): "1:87 CHEF INTERACTIONS"
  physics: {
    geometry: "tiny figures, readable_pose, NOT detailed_face"
    light: "inherits Λ_2 lighting (same studio)"
    detail: "tool_shape, body_angle, action_clear"
    color: "white_chef_coat, dark_pants, skin_tone"
    rule: "reads as NARRATIVE. Story. Whimsy."
    elements: [{{CHEF_ACTIONS}}]
    INTERACTION: "chef from Λ_3 modifies Λ_2 object"
    // knife cuts letter. bucket pours glaze. rope pulls slice.
  }

// ═══ RG FLOW RULES (how scales connect) ═══

FLOW(Λ_0 → Λ_1): "frame becomes container. Wall disappears."
FLOW(Λ_1 → Λ_2): "flat zone EXPLODES into 3D. Shadow appears."
FLOW(Λ_2 → Λ_3): "giant food becomes LANDSCAPE for tiny chefs."

// CRITICAL: each scale has DIFFERENT render engine:
  Λ_0: vector/flat (1 shape)
  Λ_1: graphic_design (grid, type, line_art)
  Λ_2: photoreal_3D (Octane/Redshift quality)
  Λ_3: miniature_photography (tilt-shift, shallow_dof)

// The FINAL IMAGE composites ALL 4 scales simultaneously.
// Viewer's eye zooms: Λ_0→Λ_1→Λ_2→Λ_3 in ~3 seconds.
// Each zoom level REWARDS with new detail.

// ═══ BOUNDARY CONDITIONS ═══
  Λ_1 ∩ Λ_2 boundary: "hard shadow line. 3D sits ON flat."
  Λ_2 ∩ Λ_3 boundary: "chef feet touch food surface. No float."
  Λ_0 ∩ Λ_1 boundary: "frame edge. Clean crop."

RENDER: {{CITY}}. All 4 Λ scales active. 1:1. Mixed media.
The poster is a WORLD at 4 resolutions simultaneously.
