some elements in dark fairyfloss theme use default colours

[hughrun]

Steps to reproduce the problem

1. apply Fairy Floss (pastel dark) theme
2. notice some elements are using the default mastodon purple rather than the Fairy Floss pink/salmon
   ...

Expected behaviour

colorscheme should override default elements

Actual behaviour

some elements are using purple default

Detailed description

Since the move to align with 4.2.10 (which I'm grateful for, thankyou!), submit buttons and .dashboard__item elements are not picking up the Fairy Floss theme like they used to but instead use the default Mastodon blurple. It looks kinda weird.

Specifications

v4.2.10+hometown-1.1.1

Similar issue on the dark fairyfloss theme, this menu is also applying incorrect colors which makes it nearly unreadable.

If preferred I can open a separate issue, too.
