# Prompt: murmur podcast hero

Build a single-file, one-screen **landing hero for a daily podcast** from a fictional show, **murmur** ("Daily Murmur Podcast"). Use plain HTML, CSS and vanilla JS, with no framework and no build step. The mood is calm and cinematic: blue hour seen through a rain-streaked apartment window, with a blurred city skyline in violet and pink, warm bokeh lights, and dark monstera leaves in the lower corners.

## Scene

- **Plate:** the whole background is ONE 16:10 image: `https://d2ol7oe51mr4n9.cloudfront.net/user_38xzZboKViGWJOttwIXH07lWA1P/7a7598ba-a6f8-42b4-ac39-98279dac4192.jpg`.
  - **Window:** a dark wooden window frame fills the middle and right. Its glass is covered in raindrops, with a blurred skyline behind it.
  - **Room:** a soft curtain hangs at the left, and big monstera leaves fill the lower-left and lower-right corners.
- **Motion:** the scene moves through a looping video of the same plate: `https://d2ol7oe51mr4n9.cloudfront.net/user_38xzZboKViGWJOttwIXH07lWA1P/d41b8c1d-f175-43b3-af22-7081133aa8de.mp4` (1280×720, 5s, muted, loops; first frame = last frame), with drops sliding and lights shimmering.
  - The video was rendered 16:9 from the plate mirror-padded 96/1728 on each side. Lay it at **111.11% width, left −5.556%** so its middle sits exactly on the plate.
  - **Lighting layers** (screen-blended, lighting only, never drawn objects):
