Adobe apps crash when dealing with CSS in generated SVG files

[dmolesUC]

Steps to reproduce:

1. From this D2 file, generate an SVG, as:
   • d2 index.d2 index.svg
2. Open the resulting file in Adobe Illustrator 2024 or Adobe Photoshop 2024.

Expected behavior:

• File opens.

Actual behavior:

• Adobe application crashes with a segfault in AdobeSVGRE.

Notes:

• Removing the generated <style/> tags allows the application to open the file (though it's then transparent-on-black and unreadable).
• Switching to the default theme doesn't solve the crashing problem (and only slightly reduces the generated file size).
• Might be solvable by optimization: tree-shake css themes #2145 and/or make a "minimal" theme #2072?

i'm actively working on inlining styles. the segfault is adobe's fault though lol

[alixander]

related: #2142

[alixander]

Let's see if it works after #2142 is fixed in the next release. If it's really the presence of <style> that's causing the crash, then we'll need to add a flag for rendering with only inline styles (e.g. --no-css or --inline-styles)

Maybe also convert text to paths

@dmolesUC can you check if D2 on the latest version still crashes?

Still crashes with 0.6.8, I'm afraid. 😕
