--- PROMPT START ---
Create a simple decision-tree infographic, 16:9 landscape, for a professional practice book on model routing for coding agents.

OUTPUT SPECS:
- 16:9 landscape; flat-vector decision tree; soft depth; print-ready
- Operational and calm — not a vendor model leaderboard

TOPIC:
Route model tiers by risk, uncertainty, and volume/latency need. Default is not maximum capability. Isolate work first. Escalate on clear triggers.

TITLE (exact):
Model routing decision tree
SUBTITLE (exact):
Default ≠ Max · Isolate first

COLOR / STYLE:
- Background #F8FAFC; navy #0B1F33; teal #0D9488 branches
- Fast tier: soft blue #2563EB
- Balanced: teal #0D9488
- Strong: amber #D97706
- Escalate: red #DC2626 accents
- Flat vector; no vendor model product names

TREE STRUCTURE:

ROOT:
"Task"

FIRST FILTERS (chips under root or first diamond row):
"Risk" · "Uncertainty" · "Volume / latency"

THREE MAIN LEAVES (equal visual weight):

A. "Fast / Cheap"
   use: "mechanical · high volume"
B. "Balanced"
   use: "standard slices"
C. "Strong reasoning"
   use: "architecture · hard bugs"

OPTIONAL small fourth leaf if space (else omit):
"Specialized" — "domain tools"

ESCALATION BAR (bottom, red/amber):
"Escalate when:"
chips: "DoD red after N" · "uncertainty flagged" · "public API / security"

BADGES (must appear somewhere as short chips):
"Default ≠ Max"
"Isolate first"

TYPOGRAPHY:
- English only; short labels
- Generic tier names only — never “GPT-…”, “Claude …”, “Gemini …” as labels
- Print-readable: title ≥40px, card titles ≥26px, body/chips ≥18px on 1376×768; no 13px slate footnotes

ALLOWED TEXT:
- Title / subtitle
- Task · Risk · Uncertainty · Volume / latency
- Fast / Cheap · mechanical · high volume
- Balanced · standard slices
- Strong reasoning · architecture · hard bugs
- Specialized · domain tools (optional)
- Escalate when: · DoD red after N · uncertainty flagged · public API / security
- Default ≠ Max · Isolate first

NEGATIVE:
- vendor logos, model version names, robots, neon leaderboards, German paragraphs, watermarks

FINAL SELF-CHECK:
Three main tiers present. Escalate triggers listed. Default ≠ Max and Isolate first visible. No vendor model names.
--- PROMPT END ---

# Follow-up edit:
# Force badges Default ≠ Max and Isolate first.
# Keep escalate triggers. Keep Specialized as the fourth tier (Kap. 5.7).
# SVG if branch geometry collapses.
