Build me a clean home screen app for LG webOS TVs that replaces the usual cluttered TV home with a fast, ad free dashboard.

It should feel like a frosted glass launcher with the main streaming apps and HDMI inputs front and center, plus live weather, sunrise and sunset info, and a few trending movie and TV picks. I want it to work on stock unrooted TVs through developer mode, install as an app on the TV itself, and not need a computer running after setup.

Make it easy to customize from the TV with the remote, so I can hide or show apps, change the theme, pick a language, and set weather or movie options. It should support the Magic Remote and normal arrow navigation, run smoothly, and include a pure black idle screen to help with OLED burn in. If you need current webOS or TMDB details, look them up online while building it.
