Triforce Architecture

Create a realistic editorial-style architecture diagram illustration 
explaining the "Triforce" cross-modal pipeline of the fumeng skill.

Visual style: Warm editorial schematic in the spirit of a classic 
engineering textbook figure crossed with Edward Tufte's visual evidence — 
reserved, precise, beautiful by clarity. Feels like a hand-drafted plate 
from a technical monograph, NOT an infographic.

Color palette:
- Background: warm cream paper oklch(0.96 0.008 40) with subtle grain
- Primary line ink: deep warm black oklch(0.18 0.02 30)
- Secondary text: muted warm grey oklch(0.50 0.01 30)
- Gold accent for active pathways: warm gold foil oklch(0.72 0.15 75)
- Terracotta accent for labels: oklch(0.58 0.19 28)

Typography:
- Figure caption title: humanist serif display (Tiempos Headline character), 
  weight 500, 48px, deep warm black: "The Triforce Pipeline"
- Node labels: monospaced letterpress type (IBM Plex Mono character), 
  14px uppercase tracking 2%, deep warm black
- Descriptive text beside nodes: warm editorial body serif 
  (PP Editorial Old character), 15px, line-height 1.6

Layout (centered equilateral triangle diagram, deliberately spacious):
- Title "The Triforce Pipeline" top-left, 48px
- Sub-caption just below title: "Three capabilities that only work together" 
  in 16px italic body serif
- Three nodes arranged in a large equilateral triangle in the center, 
  about 60% of the canvas height:
  * TOP node: a small rendered monitor showing a UI mockup inside, 
    circular stroke around it, label below in monospaced caps: 
    "IMAGE-2 · VISUAL ANCHOR". Below, 3 lines of body serif: 
    "gpt-image-2 4K mockups", "Fixes the design intent", "Accepts $0.02-0.40"
  * BOTTOM-LEFT node: a hexagonal schematic plug with six small 
    dots arrayed around it (representing 6 MCP servers), circular stroke, 
    label: "MCP · REAL ASSETS". Below: "shadcn / chrome-devtools", 
    "playwright / logo-search", "context7 / lighthouse"
  * BOTTOM-RIGHT node: a classical quill with an ink bottle, 
    circular stroke, label: "PROMPT · METHODOLOGY". Below: 
    "9 aesthetic families", "Anti-slop rules (6 banned fonts)", 
    "Placeholder > Fake philosophy"
- The three nodes are connected by thin warm gold lines with tiny circular 
  terminals at each end (like a circuit schematic), forming a triangle. 
  Each edge has a small italic caption in the middle explaining the 
  directional flow:
  * image-2 → MCP edge: "intent fixes target for harvest"
  * MCP → prompt edge: "real assets inform tokens"
  * prompt → image-2 edge: "methodology shapes the prompt"
- A subtle circular arrow at the CENTER of the triangle, with the label 
  "cross-modal loop" below it in small terracotta italic.

Bottom-right corner: a small legend:
  "— gold line = data flow"
  "— thin rule = relationship"
  "— solid stroke = active capability"

Background:
- Warm cream paper base
- Faint 8px grid visible beneath (like plotting paper but extremely muted, 
  3% opacity)
- Slight vignette at edges

Use case: Educational diagram figure in README, 1536x1024, displayed at 
reading width on GitHub.

Strict constraints:
- NO Inter, Roboto, Arial, Space Grotesk, Fraunces, system-ui fonts.
- NO purple gradients, NO holographic effects, NO glass morphism.
- NO emoji, NO cartoon characters, NO isometric 3D.
- NO dense infographic data-slop (fake percentages, fake user counts).
- All node icons must be LINE-DRAWING style (hair-line strokes), 
  not filled illustrations.
- Triangle must be GEOMETRICALLY PRECISE (equilateral), not skewed.
- All text must be EXACTLY as specified — do not hallucinate labels.
- Pixel-perfect 8px grid alignment. Letterpress restraint.
