This commit adds support for channel home pages and all of the
categories within it. However, the frontend code is a mess and thus
needs to be refactor soon. Though that would likely require a rework of
items.ecr
This commit also comes with some general cleanups and improvements.
Before this commit channel brand URls would only be supported on the
videos page (now home page). It has been improved to be able to handle
all channel URLs.
The category_type and auxiliary_data property has also been removed from
the Category struct. The former was never used and the latter allows for
random data to be added to the Struct presenting documentation issues.
Since the auxiliary_data variable was mainly used to store values from
the browse_endpoint in order to create URLs, its much simpler to instead
just get the URL from the webCommandMetadata.
As a result of this change the browse_endpoint_data attribute of
Category has also been removed.
This will prevent, on large pages, the LTR and RTL text to be
far away, on each side of the page. This could happen on channel
and playlists descriptions, when the page is displayed on a large
screen.
Adding these styles is the easiest way to add bidi (bidirectional text) support without or with least side effect. I have tested it by adding it manually on yewtu.be instance and so far it works very well.
Now that themes are controlled with a class instead of setting
media="none" on the stylesheet link and both themes already being
duplicated in default.css for the automatic themeing it makes sense
to have all theme related CSS in the same place.
This commit also fixes the missing dark theme on embeds.
Themes are now controlled with a class on the body element.
If a preference is set the body element will have either "dark-theme"
or "light-theme" class. If no preference is set or the preference is
empty the class will be "no-theme".
"dark-theme" and "light-theme" are handled by darktheme.css and
lighttheme.css respectively.
"no-theme" is handled by default.css where depending on the value of
"prefers-color-scheme" the styles corresponding to "dark-theme" or
"light-theme" are applied.
Unfortunately this means that both themes are duplicated, once in the
theme .css and once in default.css.
