Hi folks!

First of all, thank you for this great system! I've been testing Quadro and I'd like to suggest 2 modifications to the **Callouts** options, to enable better control when generating a custom **dark mode** (both HTML and PDF):

1. Add an option to customize the background color opacity for the entire callout and also its title. Reference:
/src/resources/filters/quarto-pre/callout.lua#L302
/src/resources/filters/quarto-pre/callout.lua#L303
/src/resources/filters/quarto-pre/callout.lua#L351

2. Add the **coltext** to the options and also attribute it to a variable. 

If you prefer this suggestion as a PR, please let me know. :)

Thank you,
Sergio
