# Step 0 — Pin hard constraints (MUST, before any decision)
load references/hard-constraints.md
    → Dimensions table / Safe Zones / Text Overlay Rules / Design Quality Baseline / Banned Words
keep these in working context for Steps 1, 5, 6 — violation produces fake UI artifacts,
watermarks, occluded CTAs, or platform-policy breaks.
preflight = enforce_constraints(format=null, output_text=null, prompt_text=user_request)
                                              # references/hard-constraints.md
                                              # pre-flight banned-word scan on the user request
assert preflight.pass

# Step 1 — Confirm Format and Scenario (lock dimensions first)
format = resolve_format(user_request)         # references/hard-constraints.md §Default Format Selection
    if user specified format → use it
    else apply default scenario logic:
        single image content       → Feed Portrait 4:5
        multi-page knowledge       → Carousel 4:5
        short-lived / ad           → Story 9:16
        short-video cover          → Reel Cover 9:16
dimensions, ratio, safe_zone = lookup(format) # references/hard-constraints.md

# Step 2 — Identify Industry (auto-load Visual DNA)
industry_bundle = load_industry_dna(user_request)
                                              # references/industry-dna.md
                                              # returns {prompt_patch, composition, color,
                                              # lighting, common_errors, ig_references}
                                              # on no_match → closest industry as base + adjust

# Step 3 — Define Engagement Goal
goal = SHARE | SAVE | COMMENT
    if user specified → use it
    else infer from content type:
        education / how-to     → SAVE
        lifestyle / humor      → SHARE
        opinion / debate       → COMMENT

# Step 4 — Define the Hook (3-Second Rule)
hook_type = Bold Claim | Curiosity Gap | Visual Shock
    drives Slide-1 design (Carousel) or headline strategy (single image)

# Step 5 — Composition + Color (Industry × Format cross-decision)
composition = industry_bundle.composition + safe_zone constraints
color       = brand_color (if exists, overrides) or industry_bundle.color
lighting    = industry_bundle.lighting
text        = format.text_overlay_rule (references/hard-constraints.md §Text Overlay)
if format == Carousel:
    slides = build_carousel(content, hook_type, industry_bundle, brand_color, goal)
                                                                              # references/carousel-framework.md

# Step 6 — Self-Check Gate (mandatory)
audited_output = run_workflow(user_request)
                                              # references/workflow-and-self-check.md
                                              # runs Section 2 steps + Section 4 14-item audit
findings = enforce_constraints(format, audited_output.output_text, audited_output.prompt_text)
                                              # references/hard-constraints.md
                                              # re-validates sizing, safe zone, overlay, quality, banned words
assert findings.pass
    if any item fails → revise prompt, regenerate
    if all pass       → emit self_check score block

# Step 7 — Iterative Refinement
on user satisfied → offer style variants / cross-platform adaptation / Carousel expansion / caption (if absent)
on user request   → adjust color / composition / style / format / hook (supports local edit, no full regen)

# Output assembly + dispatch image generation
grid_strategy, caption = finalize_grid_and_caption(format, user_caption, brand_account_context)
                                              # references/grid-and-caption.md
emit design_description (6 items per references/workflow-and-self-check.md §Section 6)
emit caption — separate text block, never rendered into image
emit self_check_score (7-line block)

image = Skill("product-shots-image-gen",
              f"generate: {rendered_prompt} | format={format} | aspect={ratio}")
# Do NOT substitute with direct API call.
assert image.delivered
