As a screen reader user new to Mastodon, I encountered the following issues with the column headers as designed:
 * Jumping between them was difficult. FOr instance, passing my home timeline to reach notification settings was difficult to impossible, especially considering infinite scrolling.
 * There doesn't appear to be any means for triggering the control via the keyboard. the `titleClick` handler only responds to mouse clicks.
 * I didn't even realize there was a Settings toggle until I made this change.

Thanks for using ARIA in your designs. It's a huge help. But adding a `button` role doesn't add keyboard handling and other button behavior. Also, because the role was on the heading container, it obscured the controls within the container itself. This fix resolve that. It also exposes the headings as headings rather than buttons, enabling skipping columns by using screen readers' heading navigation commands.

Since I myself am blind, if this fix requires additional visual styling, I'd like help applying that so it can be merged. I'd consider it an essential accessibility fix for my and other blind users' existence on the platform. Thanks!

* Improve Traditional Chinese translations

* Sort alphabetically

Though the subsections are representing features such as navigation and
settings, they are categorized by the ways how they are implemented
(internal navigation or external links.) They are irrelevant and some
arrangements were confusing because of that. (It is nonsense that instance
information is in settings subsection, for example.)

This fixes the issue by rearranging.

* new strings: hashtag+unlisted, mute, block

* Add confirmation step for email changes

* Add more instance stats APIs

The background of the navigation matters because its scrollbar is
transparent.

yay for regexes, amirite

Serbian latin (sr-Latn) is generated automatically from Serbian (sr) translation. Also changed some wording in original (Serbian) translation.

This version has a transparent background, which works better with the
wave.

This uses (more or less) absolute references to external assets, which
allows imported stylesheets (like components.scss) to work from other
locations that may not have the expected path structure (e.g. the win95
theme).

Relates to #6125, #6099

Getting Started column obtained many links, and it became much taller.
Because of its height, Getting Started column required long scrolling on
devices with small screen, such as 4 inch phones and 10 inch laptops.

This change moves the mastodon which took large space on the column to
drawer column. The drawer column has only the compose form and has more
space.
