`logoDark` & `logo` parameters reversed in hybrid header layout with `defaultAppearance` set to "dark"

[socrabytes]

Issue description

In config file params.toml, the header.logo and header.logoDark parameters seem to be swapped. The dark mode logo appears in light mode and vice versa. The only customization I’ve made is setting defaultAppearance = "dark" instead of the default "light", which might be related to the issue. Otherwise, no significant customizations come to mind.

defaultAppearance = "dark" 
autoSwitchAppearance = true

[header]
  layout = "hybrid" 
  logo = "img/logo-dark.png" # Bug: theme improperly handling logo versions of light/dark
  logoDark = "img/logo.png" 

This is a minor issue, but I thought it would be helpful to report it. Thank you for providing this theme and for all the effort you’ve put into maintaining it!

Does the issue still occur if the default appearance is not dark mode?

[socrabytes]

Yes, theme displays same behavior with defaultAppearance = "light"

---

I’ve also noticed something strange in Vivaldi when Windows is set to Dark Mode and the site’s default appearance is also dark. The background color doesn’t display correctly, and it looks off.

In Brave, everything works as expected — the site loads in dark mode and toggles properly to light mode. But in Vivaldi, it starts in this weird, mismatched dark mode and only switches to the correct one after toggling. This might just be a quirk with how browsers handle dark mode, but it’s still an edge case worth pointing out.

Note: The logo is currently a PNG, not an SVG, which is contributing to the display issue. Using a proper vector (SVG) logo would likely resolve this specific problem.

If I see it correctly there only needs to be a switch of hidden and dark:hidden ... the thing with flex I did not understand completly but it seems to work like I posted it below

\congo\layouts\partials\logo.html

  {{- if $logo }}
    <a href="{{ "" | relLangURL }}" class="mr-2">
      <!-- prettier-ignore-attribute -->
      <img
        src="{{ $logo.RelPermalink }}"
        width="{{ div $logo.Width 2 }}"
        height="{{ div $logo.Height 2 }}"
        class="max-h-[10rem] max-w-[10rem] object-scale-down object-left
        {{ if $logo_dark }}dark:hidden flex{{ end }}"
        alt="{{ .Site.Title }}"
      />
      {{- if $logo_dark }}
        <img
          src="{{ $logo_dark.RelPermalink }}"
          width="{{ div $logo_dark.Width 2 }}"
          height="{{ div $logo_dark.Height 2 }}"
          class="max-h-[10rem] max-w-[10rem] object-scale-down object-left hidden dark:flex"
          alt="{{ .Site.Title }}"
        />
      {{- end }}

I have the same problem.

I am also noticing this reversal in my installation. It remains the same whether defaultApperance is set to "dark" or "light".
