Ular Kimsanov a988afa00b docs: one Troubleshooting page, four tabs, and the start pages folded (#6380)
* docs: one Troubleshooting page, four tabs, and the start pages folded

* docs: keep how Studio app updates arrive on the help page

Folding the Studio app troubleshooting page into /help dropped its
"How updates arrive" section: the update button, Settings > Updates
and the Mac menu route, the Automatic updates toggle, and what to do
when an update stalls or cannot check. It is back word for word; every
label is still in the app.

Vertical media filling a 16:9 frame — three fill modes:

mirrored copies), "copy" (flanking straight copies).

elements inside a sub-composition (renders black). For live

## Add it to your video
It runs for 8 seconds at 1920×1080. Paste this into your composition:
```html index.html
<div
data-composition-id="yt-vertical-fill"
data-composition-src="compositions/yt-vertical-fill.html"
data-start="0"
data-duration="8"
data-track-index="1"
data-width="1920"
data-height="1080"
></div>
```
Move it in time with `data-start`. Put it on a different timeline row with
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
{/* hf:generated-footer */}
Tagged `placeholder` `vertical` `media`.
