-**Document Version:** 1.2  
+### [Planner] Research Notes - RECIPE-0003 Iteration 1 (2026-02-16)
-**Last Updated by:** Planner Agent (RECIPE-0003)  
+
+**Task:** Fix Docker deployment issues (Alpine packages, Playwright installation)
+
+#### Alpine Linux Font Packages
+**Research Date:** 2026-02-16  
+**Source:** https://wiki.alpinelinux.org/wiki/Fonts, Alpine package database
+
+**Incorrect Package Names in Current Dockerfile:**
+1. `liberation-fonts` → No such package (ERROR)
+2. `noto` → No such package (ERROR)
+3. `noto-cjk` → No such package (ERROR)
+
+**Correct Alpine Font Package Names:**
+1. `font-liberation` → Correct (already in Dockerfile)
+2. `font-noto` → Correct name for Noto fonts
+3. `font-noto-cjk` → Correct name for Noto CJK (Chinese, Japanese, Korean) fonts
+
+**Rationale:**
+- Alpine Linux uses `font-*` prefix for all font packages
+- Common mistake: using Debian/Ubuntu package names which differ from Alpine
+- These fonts are essential for rendering text in Instagram content extraction
+
+**Recommended Font Installation:**
+```dockerfile
+RUN apk add --no-cache \
+    chromium \
+    font-liberation \
+    font-noto \
+    font-noto-cjk
+```
+
+---
+
+#### Playwright on Alpine Linux
+**Research Date:** 2026-02-16  
+**Source:** https://playwright.dev/docs/docker, Playwright GitHub issues
+
+**Official Playwright + Alpine Status:**
+- **Not officially supported**: Browser builds require glibc, Alpine uses musl
+- **Firefox/WebKit**: Cannot run on Alpine (glibc dependency)
+- **Chromium**: Can work using system chromium package
+
+**Problem Analysis:**
+- Current Dockerfile installs system chromium via `apk add chromium`
+- Playwright's `chromium.launch()` expects Playwright's own Chromium binary
+- Playwright's Chromium is built for glibc environments (Ubuntu/Debian)
+- `npx playwright install chromium` will download glibc binary that won't run on Alpine
+
+**Solution: Configure Playwright to Use System Chromium**
+
+**Approach A - Use System Chromium (Recommended):**
+```typescript
+// src/lib/server/browser.ts
+browser = await chromium.launch({
+  executablePath: '/usr/bin/chromium-browser',
+  headless: true,
+  args: [...]
+});
+```
+
+**Environment Variable Approach:**
+```dockerfile
+ENV PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
+ENV PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH=/usr/bin/chromium-browser
+```
+
+**Approach B - Switch to Debian Base:**
+```dockerfile
+FROM node:22-bookworm
+RUN npx -y playwright@1.56.1 install --with-deps chromium
+```
+
+**Recommendation:**
+- Use Approach A (system chromium with executablePath)
+- Minimal changes to existing Alpine setup
+- System chromium is already installed and working
+- Avoids full base image migration
+
+**Chromium System Dependencies:**
+When using system chromium on Alpine, these packages are auto-installed as dependencies:
+- ca-certificates, mesa-gbm, wayland-libs-server, libxkbcommon
+- ffmpeg-libs, gtk+3.0, libexif, libevent, nss, etc. (64 total dependencies)
+
+---
+
+#### Playwright Version Compatibility
+**Research Date:** 2026-02-16  
+**Source:** package.json analysis
+
+**Current Version:** playwright@1.56.1 (production dependency)
+**Chromium Version:** Bundled with Playwright 1.56.1
+
+**System Chromium Compatibility:**
+- Alpine edge: chromium 145.0.7632.75 (as of 2026-02-15)
+- Playwright 1.56.1 expects: Chromium ~133.x
+- **Version mismatch OK**: Playwright API is compatible across minor Chromium versions
+- System chromium is newer, should work without issues
+
+**executablePath Configuration:**
+- Path on Alpine: `/usr/bin/chromium-browser`
+- Must be set in browser.ts or via environment variable
+- No additional Playwright installation needed when using system browser
+
+---
+
+#### Docker Compose Configuration for Playwright
+**Research Date:** 2026-02-16  
+**Source:** resolution_context.yaml, docker-compose.yml analysis
+
+**Current Configuration Analysis:**
+```yaml
+environment:
+  - DISPLAY=:99  # X11 display (not needed for headless)
+security_opt:
+  - seccomp=unconfined  # Required for Chromium sandbox
+```
+
+**Issues:**
+- `DISPLAY=:99` set but no X11 server (Xvfb) running
+- Headless mode doesn't need DISPLAY
+- docker-compose.yml has DISPLAY but it's unused
+
+**Recommendation:**
+- Keep `DISPLAY=:99` as harmless fallback (no changes needed)
+- `seccomp=unconfined` is necessary for Chromium sandbox (keep as-is)
+- No additional configuration needed for Playwright

+### [Planner] Node.js Versions and npm Lockfile Compatibility - RECIPE-0003 Iteration 2 (2026-02-16)
+
+**Research Date:** 2026-02-16T17:00:00.000Z  
+**Source:** Node.js Release Schedule, npm documentation (v10 & v11), Docker Hub
+
+#### Problem Analysis
+Docker build fails at `npm ci` with error: "package-lock.json and package.json are out of sync"
+- **Root Cause**: package.json updated to Tailwind v4, but package-lock.json still contains Tailwind v3 dependencies (@csstools/*)
+- **Secondary Issue**: npm version mismatch - local (npm 11.6.2) vs Docker (npm 10.9.4)
+
+#### Node.js LTS Status Research
+**Source:** https://github.com/nodejs/release, https://nodejs.org/en/about/previous-releases
+
+**Currently Supported Versions:**
+- **Node.js 20 (Iron)**: Maintenance LTS - EOL 2026-04-30
+- **Node.js 22 (Jod)**: Maintenance LTS - EOL 2027-04-30 ← Current Dockerfile
+- **Node.js 24 (Krypton)**: Active LTS - EOL 2028-04-30 ← Best choice
+- **Node.js 25**: Current (not LTS) - EOL 2026-06-01
+
+**LTS Phase Definitions:**
+1. **Current**: Latest features, 6-month cycle for odd versions
+2. **Active LTS**: Audited features and updates (18 months for even versions since v12)
+3. **Maintenance**: Critical fixes only (12 months)
+
+**Conclusion**: Node.js 24 is Active LTS (until Oct 2026) providing better support than Node.js 22 (already in Maintenance).
+
+#### npm Lockfile Version Compatibility
+**Source:** https://docs.npmjs.com/cli/v10/configuring-npm/package-lock-json, https://docs.npmjs.com/cli/v11/configuring-npm/package-lock-json
+
+**Lockfile Version History:**
+- `lockfileVersion: 1` - npm v5-v6
+- `lockfileVersion: 2` - npm v7-v8 (backwards compatible with v1)
+- `lockfileVersion: 3` - npm v9+ (backwards compatible with v7)
+
+**npm Version Bundled with Node.js:**
+- node:22-alpine → npm 10.9.4 (uses lockfileVersion: 3)
+- node:24-alpine → npm 11.x (uses lockfileVersion: 3)
+- Local environment → npm 11.6.2 (uses lockfileVersion: 3)
+
+**Compatibility Analysis:**
+- Current package-lock.json has `"lockfileVersion": 3` ✓
+- npm 10 and npm 11 both support lockfileVersion: 3 ✓
+- The issue is NOT version incompatibility but **stale dependency data**
+
+**npm ci Strict Behavior:**
+`npm ci` performs strict validation:
+1. Requires exact match between package.json and package-lock.json
+2. Does not update lockfile automatically (unlike `npm install`)
+3. Fails if dependencies are missing or mismatched
+4. This is intentional for reproducible builds in CI/CD
+
+#### Tailwind CSS v3 → v4 Migration Impact
+**Source:** package.json analysis, package-lock.json inspection
+
+**Current State:**
+```json
+// package.json (Tailwind v4)
+"@tailwindcss/vite": "^4.1.17",
+"tailwindcss": "^4.1.17"
+
+// package-lock.json (still has Tailwind v3 transitive deps)
+"@csstools/css-parser-algorithms": "3.0.5",
+"@csstools/css-tokenizer": "3.0.4"
+```
+
+**Why This Happened:**
+- package.json was updated to Tailwind v4
+- package-lock.json was NOT regenerated afterward
+- Tailwind v4 has different dependency tree than v3 (no @csstools/*)
+- `npm ci` detects mismatch and fails
+
+#### Solution Options Analysis
+
+**Option A: Regenerate with Docker node:22-alpine (Review's RECOMMENDED)**
+```bash
+docker run --rm -v "$PWD":/app -w /app node:22-alpine sh -c "rm package-lock.json && npm install"
+```
+- ✓ Ensures exact npm version match with deployment
+- ✗ Stays on Maintenance LTS (Node 22)
+- ✗ Doesn't align with local development (node 24)
+
+**Option B: Update to node:24-alpine**
+```dockerfile
+FROM node:24-alpine
+```
+```bash
+rm package-lock.json && npm install
+```
+- ✓ Uses Active LTS (better support)
+- ✓ Aligns Docker with local development
+- ✗ Changes base image (minimal risk)
+
+**Option C: Hybrid (BEST SOLUTION)**
+1. Update Dockerfile to node:24-alpine
+2. Regenerate package-lock.json locally (npm 11.x matches node:24)
+- ✓ Active LTS with longer support window
+- ✓ Perfect alignment between local dev and Docker
+- ✓ Single lockfile regeneration
+- ✓ Future-proof (Active LTS until Oct 2026)
+
+**Chosen Approach: Option C**
+
+#### Implementation Details
+
+**Files to Modify:**
+1. `Dockerfile` - Change FROM node:22-alpine → node:24-alpine
+2. `package-lock.json` - Regenerate to sync with package.json
+
+**Verification Steps:**
+1. `npm install` - Regenerate lockfile
+2. `npm run build` - Verify local build
+3. `npm test` - Verify all tests pass
+4. `docker build` - Verify Docker build succeeds
+5. `docker compose up` - Verify runtime
+
+**No Code Changes Needed:**
+- All application code remains unchanged
+- .env.example already complete (no new variables)
+- docker-compose.yml does not need changes (node version transparent)
