# Prompt: Reelmark hero

Build a single-file, one-screen **landing hero for a short-form video creator marketplace**, **Reelmark** ("Captivate Crowds with Snackable Reels"). Use plain HTML, CSS and vanilla JS, with no framework and no build step. The look is soft mint studio: a warm off-white page `#F5F8EF`, deep forest-green accents `#08482D`, a mint badge `#DAE7C7`, a big bold black headline, and an arched row of seven tall video cards playing bright sage-green product clips, with hand-drawn green notes and arrows.

## Frame

- **Frame:** one **1440×1080** frame, contained and centred: `--u = min(100vw/1440, 100vh/1080)`. Every element is placed in frame units.

## Type

- **Headline:** **Inter Tight 700**, 88u on a 92u line, tracking −0.035em (−0.022em on line 2), ink `#101410`.
- **UI:** **Inter** 400/500. The subline is `#5E5E61`.
