🖼️ Artifact Gallery: Visual showcase of 5-6 real generated artifacts in README #14

🎯 Feature: Artifact Gallery in README

Context

The README.md is the first touchpoint for any potential user. Currently it describes what html-explainer does in abstract terms but does not show what the output actually looks like. This is a critical gap: visual-first decisions happen within seconds. A user who cannot see a screenshot or a live example will not install the tool.

A gallery section with real screenshots of generated artifacts — showing actual decision decks, diff reviews, architecture diagrams, and recaps — converts curious visitors into users by demonstrating real value before they invest any time.

Problem

• README describes capability in words; without visual proof, users must imagine the output
• New users cannot evaluate whether the output quality meets their bar without running the tool
• Artifact patterns are listed by name but not illustrated, making it hard to understand which pattern solves which problem
• The tool has no standalone proof of value — it requires installation to see anything

What This Resolves

• A Visual Artifact Gallery section in README.md showing 5-6 real artifact screenshots
• Each gallery item includes: pattern name, artifact type, key visual elements, and the URL to the live example
• Gallery demonstrates the range of artifact types (decision, review, architecture, workflow, recap, research)
• Makes the tool output tangible before installation — the README becomes the demo

Proposed Approach

Gallery Section (add to README.md after "What Good Output Looks Like"):

Each gallery item shows:

• Pattern number and name
• One-line description of what the artifact contains
• Key structural element (e.g., "Comparison matrix + recommendation")
• Link to the live example HTML file in the repo

Gallery manifest (examples/gallery-manifest.json):

[
 {
 "pattern": "11-technical-decision-deck",
 "example_path": "examples/before-after-decision.example.html",
 "artifact_type": "decision-deck",
 "summary": "Compare 2-4 options with scores, risks, and recommendations",
 "key_elements": ["comparison matrix", "risk level", "recommendation", "next action"]
 }
]

Acceptance Criteria

• README.md contains a gallery section with at least 6 rows (one per pattern type)
• Each gallery row links to a real, verifiable HTML example in the examples/ directory
• Gallery renders correctly on GitHub.com (light + dark mode compatible)
• examples/gallery-manifest.json exists and lists all gallery items
• validate-examples.sh checks that all gallery-referenced examples exist and are valid HTML
• All gallery-referenced examples pass audit-artifact.py at 90+
• Screenshot generation script examples/generate-screenshots.sh exists (even if not run in CI yet)

Quality Verification

Verify all gallery examples exist, pass audit at 90+, and README contains the gallery section. Run the validation script to confirm.
