Terminal: iTerm2 or Warp, dark theme, 14pt monospace. Clear history (clear, then close and reopen the tab so scrollback is empty).
Shell: cd into a fresh empty directory — e.g. /tmp/stack-demo. Nothing else in it.
Browser: have a Supabase tab open and already logged in so the OAuth consent screen loads instantly, not the login screen.
Window layout: terminal takes ~65% of screen width, browser on the right. Record at 1920×1080 or retina 2x.
Homebrew tap already added in PATH — confirm which stack returns nothing before starting (verifies clean state). If stack is already installed, brew uninstall ashlrai/ashlr/stack first so the install step is real.
Zoom: bump terminal font to 16pt for recording legibility.
Switch visual focus to browser for 3–4s, then back to terminal as spinner runs: provisioning supabase… ✓

SDK install prompts
(automatic — part of init flow)
Terminal: install @supabase/supabase-js? (Y/n) → Y; install posthog-js? (Y/n) → Y; spinner for each
Terminal — type Y for each prompt, watch the install spinners

Boot the app
stack exec -- bun dev
bun dev output: ready - started server on 0.0.0.0:3000
Terminal, then quick pan to browser

Browser shows live app
(switch to browser, open localhost:3000)
Next.js default page loads; Supabase health indicator green
Browser — hold 2–3s, then cut to end card

Thumbnail suggestion: Dark terminal background, two-column layout. Left: the chaos side — six browser tabs open, .env.local with redacted keys. Right: clean terminal with stack init --template nextjs-supabase-posthog and green checkmarks. Text overlay: "39 providers. One command." in the Inter/Geist font used on the site. No stock photos.
Caption (for YouTube / X post):
39 providers. One command.
Stack v0.2 — stack init --template nextjs-supabase-posthog provisions Supabase, installs the SDKs, wires Phantom secrets, and boots your app in under 60 seconds.
