## Issue
Part of `7166 improve search metadata`
## Notes
This is an experiment to influence the Sitelinks in our search results. Our current sitemap only consists of claims, so claims appear in Sitelinks more often. We (Julian) want categories to have higher priority, if possible.
For now, the sitemap will be defined in Google Console instead of robots.txt.
If it works, the file should be uploaded to sitemap.odysee.com, alongside the claim list sitemap.
## Issue
Category cards are showing up as "odysee.com" cards in Facebook.
## Change
- `og:url` is supposed to be the canonical URL. It was hardcoded to "odysee.com", so every category was being redirected when the card is being generated.
- Removed `twitter:url`. The documentation says it will fall back to `og:url`, so there is not need to define both if it's the same.
- A side-quest from "7166 improve search metadata".
- The favicon must be from the same domain as the homepage, so the CDN URL couldn't be used, hence the additional upload.
- The favicon also needs to be multiples of 48x48 and above.
- Wanted to use SVG for the smallest size possible, but seems like Safari does not fully support it. Got Dejan to give me a reasonably-sized PNG.

## Issue
7166 improve search metadata
Depending on the search term and timing, Google extracts data from the sidebar or page content to use as the search-result description.
## Change
Defined `description` (on top of the existing `og:description` and `twitter:description`.
While I couldn't find a definitive doc saying that this is the solution, this is present in all other sites (and matches their description in a Google Search results).

## Issue
5848 Remove scroll-bar in update prompt
## Changes
- Make scrollbars appear only when necessary.
- Style the scrollbar. Similar to other areas, we skip this for Mac (can't recall why we need to skip).
## Issue
`https://github.com/lbryio/lbry-desktop/issues/6369#issuecomment-882081892`
## Changes
- Replace 'feed' with 'node-rss' for itunes spec support.
- Replace content type from 'rss+xml' to 'xml' so that the browser will display it nicely using the document tree without us having to re-format it ('node-rss' does not). Seems like all feeds that I found does it this way.
- There is no need to escape characters now that 'node-rss' does it. Nice.
## Issue
5951: OG messed up if `$"` is in title
The replacement string would contain `...$"...`. The character `$&` has special meaning in `replace`, so the output was messed up.
## Approach
Use a direct slice approach. A bit less elegant.
