--- PROMPT START ---
Create a premium side-by-side stacked budget comparison infographic, 16:9 landscape, for a professional engineering practice book about LLM-based coding agents and context engineering.

OUTPUT SPECS:
- Aspect ratio: exactly 16:9 landscape
- Look: clean flat-vector editorial illustration with soft depth (subtle shadows, frosted panels), high resolution, print-ready, grayscale-safe contrast
- NOT a photo, NOT 3D cyberpunk, NOT a vendor cost dashboard screenshot

TOPIC (must be correct):
How you allocate the context budget determines quality. Left = Sweet Spot / high signal. Right = Dumb Zone / rot. Percent shares are illustrative tendencies, not measured benchmarks.

TITLE (exact spelling, top-center or top-left):
Context budget: Sweet Spot vs Dumb Zone
SUBTITLE (exact):
allocate signal — starve noise

COLOR / STYLE (mandatory):
- Background: warm off-white / soft paper (#F8FAFC to #F1F5F9)
- Structure navy: #0B1F33
- Slate secondary: #334155
- Left column accent: sweet-spot green #16A34A + signal teal #0D9488
- Right column accent: dumb-zone amber #D97706 + risk red #DC2626
- Soft blue #2563EB only for “history” segments if needed
- Generous margins; calm professional mood; high print contrast

COMPOSITION — TWO EQUAL COLUMNS:

LEFT PANEL — header badge green:
"Sweet Spot · high signal"
One tall vertical stacked bar (or equal-height stack) with clear segment labels (short English). Approximate illustrative shares (mark as tendencies):
1. top thin: "System + AGENTS.md" ~12–15% — navy/slate
2. "Skills" ~5% — teal
3. "Task + DoD" ~15–20% — green (visually prominent, near top/upper third so DoD is not buried)
4. "Short history" ~20–25% — soft blue
5. "Filtered tools" ~30% — teal (largest useful work segment)
6. bottom thin: "Buffer" — light slate
Optional micro-chips under bar: "signal high" · "cost controlled"

RIGHT PANEL — header badge red/amber:
"Dumb Zone · rot"
Matching tall stacked bar, same overall height:
1. "Bloated history + failed tries" ~40–45% — largest amber/red (noisy)
2. "Unfiltered logs / JSON" ~30–35% — red-amber
3. "Stale rules" ~10–15% — slate muted
4. "DoD buried mid" ~10% — small green crushed in the middle (Lost-in-the-Middle visual cue)
Optional micro-chips: "noise high" · "tokens expensive"

CENTER or BOTTOM CALLOUTS (max 3 short chips total across whole figure):
- "signal / noise"
- "token cost"
- "symptoms: DoD lost mid"

TINY FOOTER (exact):
"shares are tendencies, not benchmarks"

TYPOGRAPHY RULES:
- All visible words correct English spelling only
- Short labels only; no paragraphs; no German body text
- Prefer dropping a micro-chip over inventing filler text
- Never render prompt meta (no “16:9”, hex codes, “quality guardrails”) as labels

ALLOWED TEXT ON THE IMAGE (priority whitelist — drop secondary if crowded):
- Title and subtitle as above
- Column headers: Sweet Spot · high signal | Dumb Zone · rot
- Segment labels: System + AGENTS.md · Skills · Task + DoD · Short history · Filtered tools · Buffer · Bloated history + failed tries · Unfiltered logs / JSON · Stale rules · DoD buried mid
- Chips: signal high · cost controlled · noise high · tokens expensive · signal / noise · token cost · symptoms: DoD lost mid
- Footer: shares are tendencies, not benchmarks

VISUAL QUALITY:
- Both bars same height for fair comparison; segments clearly separated
- DoD segment is easy to find on left and clearly crushed/buried on right
- Readable at book width; soft matte depth only

NEGATIVE / FORBIDDEN:
- robots, mascots, brand logos, watermarks, neon gauges, fake dollar invoices
- inventing precise scientific claims; claiming percentages are measured data
- German paragraphs, product model names, photoreal UI screenshots

FINAL SELF-CHECK:
Two columns only. Left healthy allocation with DoD visible. Right noise-dominated with DoD buried. Footer tendency disclaimer present.
--- PROMPT END ---

# Follow-up edit:
# Keep left DoD upper/visible; right DoD mid-buried. Equal bar heights.
# Preserve tendency footer. Drop chips before garbling percentages.
# Prefer SVG if segment order or % labels collapse.
