Describe the Bug

The linked repro has this implementation:

• dark theme @ astro dev
• light theme @ astro build
• 2 pages, one which loads the theme via CSS and the other via SCSS

 

✔️ astro dev @ [CSS, SCSS]

 

❌ astro build @ [CSS, SCSS]

Styles are broken for all pages, not just the ones that loaded SCSS.

Update:
I was just exploring this a bit more and now can't reproduce the CSS page being broken when other pages have SCSS...
Also ran into that several times yesterday, so CSS being affected in the presence of SCSS seems intermittent.
The SCSS issue is consistent.

 

✔️ astro build @ [CSS]

(SCSS page renamed to SCSS.astro.disabled)
