+## Pre-Launch Checklist
+
+### Screenshots Needed (from PR #4)
+
+Capture these from https://github.com/RemoteState/pencil-actions/pull/4:
+
+1. **`docs/images/demo-diff-review.png`** — The diff mode PR comment showing before/after tables. This is the hero image for the README and social posts. Capture the section starting from "Design Review" header through the collapsed unchanged frames.
+
+2. **`docs/images/social-preview.png`** (1280x640px) — Social preview image for the GitHub repo. Upload via GitHub Settings > Social Preview. Could be a composite of the YAML config + the PR comment result.
+
+3. **`docs/images/yaml-config.png`** — Screenshot of just the 5-line workflow YAML from the Quick Start section.
+
+4. **`docs/images/split-screen.png`** — Split-screen graphic: YAML config on left, PR comment result on right. This is the strongest visual for social posts ("You write THIS, you get THAT").

+## Phase 1: Philosophy Post (Day -1)
+
+### LinkedIn
+
+```
+Hours of planning can save you weeks of coding.
+
+We've all heard it. But in the AI era, it hits different.
+
+When code is nearly free to generate, the bottleneck isn't
+implementation — it's knowing what to implement. Direction > speed.
+
+I've seen teams ship 3 versions of a feature because no one
+stopped to design the flow first. AI made each version fast.
+But fast x wrong direction = expensive.
+
+The teams winning right now aren't the ones coding fastest.
+They're the ones thinking hardest before the first line is written.
+
+Design first. Brainstorm with AI. Flush out the UX. Get everyone
+on the same page. THEN implement.
+
+The irony? AI is the best brainstorming partner we've ever had.
+But most teams skip that step and go straight to "build me a
+login page."
+
+What's your take — are we moving too fast to think?
+```
+
+**Why this works**: Engages people in a debate. Gets comments. Algorithms love engagement. Sets up the product announcement as the natural follow-up.
+
+---
+
+## Phase 2: Launch Post (Day 0)
+
+### LinkedIn Launch
+
+```
+We open-sourced our internal design review tool.
+
+5 lines of YAML → every design change in your PR gets
+a visual diff. Before and after. Automatically.
+
+Here's what it looks like:
+[ATTACH: split-screen.png or demo-diff-review.png]
+
+Why we built this:
+
+At RemoteState, we adopted design-first development.
+Designs versioned in git, treated like code. AI for
+brainstorming, Pencil for designing, code last.
+
+But something was missing. When a designer updated 3 screens
+out of 20, the PR just showed a blob of JSON changes.
+No one could tell what actually changed visually.
+
+So we built this. A GitHub Action that:
+
+-> Detects which .pen design files changed
+-> Compares the base branch version with the new one
+-> Renders only the changed frames
+-> Posts before/after screenshots right in the PR
+
+It's been running on our projects for months.
+Today we're making it free for everyone.
+
+1,000 screenshots/month. No API key. No account.
+Just add the workflow file and push.
+
+github.com/RemoteState/pencil-actions
+
+Using Pencil for your product? Tell us about it ->
+remotestate.com/contactus
+We'll bump you to 10,000 screenshots/month. For free.
+
+We just want to hear what you're building.

+### Twitter Launch
+
+**Single tweet:**
+
+```
+We open-sourced our design review tool.
+
+5 lines of YAML → visual diffs in your GitHub PRs.
+
+Before/after screenshots for every design change. Automatic.
+
+→ Free (1,000/month)
+→ No API key needed
+→ Works with @pencaboratory .pen files

+Tweet 1:
+We've been running visual design diffs in our PRs for months.
+
+Today we're open-sourcing the tool. Free for everyone.
+
+Here's the story and why we built it →
+
+Tweet 2:
+The problem: Design files in git look like JSON blobs.
+
+A designer changes 3 screens out of 20. The PR diff? Useless.
+
+No one knows what actually changed without opening the design tool.
+
+Tweet 3:
+So we built a GitHub Action that:
+
+1. Detects changed .pen design files
+2. Fetches the old version from the base branch
+3. Compares frame-by-frame
+4. Posts before/after screenshots in the PR
+
+[ATTACH: demo-diff-review.png]
+
+Tweet 4:
+The philosophy: design should be version-controlled
+and reviewed like code.
+
+Not "export a PNG and paste it in Slack."
+
+Actual visual diffs. In the PR. Where your team already reviews work.
+
+Tweet 5:
+Setup is 5 lines of YAML:
+
+[ATTACH: yaml-config.png]
+
+That's it. Free tier: 1,000 screenshots/month per repo.
+No API key, no account — just GitHub OIDC.

+### Hacker News
+
+**Title**: `Show HN: Visual design diffs in GitHub PRs – open-source GitHub Action for .pen files`
+
+**Body**:
+
+```
+We built a GitHub Action that adds visual design review to pull requests.
+
+When .pen design files change in a PR, it automatically:
+- Detects which frames (screens) changed
+- Renders before/after screenshots
+- Posts a comment with side-by-side comparison
+- Collapses unchanged frames
+
+It's the same review flow developers use for code, but for designs.
+
+Setup is a 5-line workflow YAML file. Free tier is 1,000 screenshots/month
+per repo with no API key needed (uses GitHub OIDC).
+
+We built this internally at RemoteState because we version our designs in git
+and needed actual visual diffs in PRs instead of unreadable JSON changes.
+
+GitHub: https://github.com/RemoteState/pencil-actions
+Example PR with design diff: https://github.com/RemoteState/pencil-actions/pull/4
+
+Works with Pencil (.pen) design files.
+```
+
+### Reddit
+
+**Subreddits**: r/programming, r/webdev, r/github
+
+**Title**: `We open-sourced a GitHub Action for visual design diffs in PRs — before/after screenshots for .pen files, free`
+
+**Body**:
+
+```
+We've been running visual design review in our PRs internally for a while
+and just open-sourced it.
+
+It's a GitHub Action that detects changed .pen design files, compares
+the base branch version with the new one frame-by-frame, and posts
+before/after screenshots right in the PR comment.
+
+- 5-line YAML setup
+- Free: 1,000 screenshots/month per repo
+- No API key needed (uses GitHub OIDC)
+- Only renders changed frames (smart diffing)
+
+Repo: https://github.com/RemoteState/pencil-actions
+Example PR: https://github.com/RemoteState/pencil-actions/pull/4
+
+Works with Pencil (.pen) design files — the design tool that's been
+getting a lot of attention lately.
+
+Would love feedback from anyone who versions design files in git.
+```

+
+## Phase 3: Follow-Up Content (Day +2 to +7)
+
+### "Behind the Build" (Day +2, LinkedIn)
+
+Technical post about:
+- SHA-256 frame hashing for change detection
+- Frame matching by stable IDs across versions
+- The async job queue (why sync screenshots hit Cloudflare 504s)
+- Docker master/worker architecture for scaling
+- Why we chose GitHub OIDC over API keys for the free tier
+
+### "5-Minute Setup" (Day +3, Dev.to / blog)
+
+Step-by-step tutorial:
+1. Create `.github/workflows/design-review.yml`
+2. Push a `.pen` file change
+3. See the comment appear
+4. Show the before/after result
+
+Include screenshots of each step.
+
+### Engagement Post (Day +5, Twitter)
+
+```
+What's the worst design review process you've ever seen?
+
+I'll start: "Export screens as PNGs, upload to Google Drive,
+paste links in the PR description, hope someone looks at them."
+```
+
+### Traction Update (Day +7, LinkedIn)
+
+```
+One week ago we open-sourced Pen Design Review.
+
+[X] repos have added it. [Y] design diffs generated.
+
+Here's what we learned from the first week...
+```
+
+---
+
+## Viral Mechanics — Why This Can Work
+
+1. **Visual product = visual content**: The before/after screenshot IS the demo. No explanation needed.
+2. **Trending wave**: Pencil is getting attention → people searching for Pencil tooling will find this.
+3. **Zero friction**: "Add 5 lines, get design review" — tryable in 2 minutes.
+4. **Free removes objections**: No pricing page, no sign-up, no "contact sales."
+5. **CTA creates conversations**: "Tell us about your project, get 10x credits" — not selling, connecting.
+6. **Dev tool Show HN formula**: Open source + real problem + good demo = front page potential.

+# Screenshot Placeholders
+
+These images need to be captured manually and placed in this directory.
+
+## Required Images
+
+### 1. `demo-diff-review.png` (README hero image)
+
+**Source**: https://github.com/RemoteState/pencil-actions/pull/4
+**What to capture**: The diff mode PR comment (the one tagged `pencil-design-review:diff`).
+
+It shows:
+- "Design Review" header
+- "1 design file (1 modified)" + "Frames: 3 modified, 6 unchanged"
+- Before/after tables for Dashboard, Analytics, and Settings
+- Collapsed "6 unchanged frames" section
+- "Generated by Pencil Design Review" footer
+
+**Tip**: Use browser DevTools to set width ~900px for a clean capture. Crop tightly around the comment body.
+
+### 2. `social-preview.png` (1280x640px)
+
+**Purpose**: GitHub repo social preview (Settings > Social Preview)
+**Content**: Could be a composite showing the value prop:
+- Left: the 5-line YAML config
+- Right: the resulting PR comment with before/after screenshots
+- RemoteState branding
+
+### 3. `yaml-config.png`
+
+**Source**: The Quick Start YAML from the README
+**What to capture**: Just the clean 5-line workflow snippet
+
+### 4. `split-screen.png`
+
+**Purpose**: Primary social media visual
+**Content**: Side-by-side showing:
+- Left side: The minimal YAML config (effort)
+- Right side: The PR comment with before/after screenshots (result)
+
+This is the strongest visual for social posts — shows effort vs. reward.
