Shipped the public landing page — mascot art, bilingual, a real-capture carousel, and a demo video

What shipped

A single self-contained static page (landing/index.html, no build step), now live at ddalkkak.daeseon.ai:

• Mascot art, honestly. The cyberpunk-sloth illustrations are the hero banner, three roomy left/right "explainer" bands, and the Download app-icon — never dropped into a screenshot-shaped frame. The real-product carousel is kept visually distinct, so the art never reads as the UI.
• Bilingual, English-first. A nav toggle swaps the whole page (nav, hero, bands, download, footer, and the JS-built carousel captions + demo placeholder) between EN and KO. One source — English lives in the HTML, Korean in a KO dict; choice persists (localStorage) and is shareable via ?lang=ko. No file duplication.
• A data-driven capture carousel. Screenshots come from one SHOTS list at the bottom of the file; the carousel (‹ › arrows, swipe, arrow keys, dots) rebuilds to however many you list — one shot hides the controls, many page through. Missing files show a "coming soon" placeholder, never a broken image. Shipped with 4 real captures (multi-pane cockpit with Claude and Codex panes; Usage Pulse; the ⌘I summary card; the ⌘L log).
• A demo video. A ~1.5-min real-session recording (62 MB → 4.6 MB via ffmpeg x264 CRF 30 — screencasts compress beautifully) shown with a poster + click-to-play controls and preload="metadata", so the page stays fast and the video only downloads on play.
• Deploy: Vercel CLI from the landing/ folder onto the existing ddalkkak.daeseon.ai domain. Hi-res illustration masters are kept out of the deploy via .vercelignore.

One gotcha worth remembering: Safari obeys EXIF orientation, Chrome (in my pipeline) didn't

One illustration (focusup) rendered rotated 90° in Safari but upright in Chrome. Cause: a stray EXIF orientation tag — sips reported the pixels as landscape, but mdls/ImageIO (Safari's engine) read it as portrait and rotated it. The fix was to bake the rotation into the pixels and re-encode (verified with QuickLook as the Safari-engine oracle). Always check mdls -name kMDItemOrientation X.jpg is 0 after converting images — a renderer that respects EXIF will rotate what another renderer leaves alone. (Documented in landing/README.md.)
