## Issue
https://www.notion.so/Performance-Fixes-927f825a5d674bd09323830be1d263af#1beab2fee011421492b56b88f68681a3
We currently lazy-load the tiles in the category sections (but not the sections themselves, because we want to retain scroll position on Back action). This puts gray placeholders until the section is visible on screen. which turns out to be quite expensive, because the placeholders are animated, so we have a perpetual animation in the background after the homepage loads + user did not scroll.
## Change
Just disable the barely-noticeable animation for now.
There are alternatives, but probably not worth polluting the code with:
- Just like the thumbnails, use intersection observer to decide when to animate.
- Find solution to the "lazy load section + need to retain scroll position".

Now that we have a dedicated chromecast button, we don't need to hack Chrome's default cast button to appear on top of vjs-mobile-ui. The hack no longer works anyway, since the CSS exposure has been deprecated around mid 2020 -- it is still available, but its abilities has become less and less.
- The graphic was meant to be 50% of the card width, but was squished.
- Try to reduce scrolling by making everything fit in a 100% zoom on a 1080p screen.
- More css consolidation.
- More size and padding restoration (it wasn't 445's main intention to change sizes).
- Handle padding for mobile to hopefully make everything fit, especially for Playlists. We'll need an overflow menu to truely fix this for all screens.
## Issues
- So many `!important` overrides that makes it hard to customize.
- Weird "813px max-width" check -- it feels random, plus does not adjust accordingly to zoom-levels.
- The button text is not always vertically centered for all layout and zoom-levels because it is being centered using hardcoded margins.
- The 2 popups don't have consistent fonts and styling, plus their customizations are all over the place.
## Changes
- Try to remove as many unnecessary "!important" as possible. Adding specificity is sufficiently, and won't block other customizations.
- Try using `rem` instead of hardcoded margins. The icons/text/margin should resize accordingly per zoom-levels.
- I didn't replicate the "813px max-width" media check. If it is really necessary, please use `vjs-layout-*` to customize them instead.
- Consolidate the 2 popup menu customizations.
Each button should have the same touch area and roughly the same left-right margins. Currently, the Theater Button (or the Chromecast button) looks too far from Speed and too close from Autoplay. They should be evenly-spaced.
