fix: DC-4818 Add default color for code blocks' span

[carlagn]

Color on code's spans is defined inline, in order to get token highlighting working.
From reports on the issue/slack thread, it seems that this highlighting was taking a bit more time to resolve, so I've added a default color to fall back on, which is the most contrasting for both light and dark mode.

This should minimise the visual impact.

31-34: Add fallbacks in var() to avoid silent no-op if --primary-font-color is undefined

Good addition. To make this more resilient across themes, add a fallback chain so we gracefully fall back to Prism’s base code color or inheritance if --primary-font-color isn’t defined.

-    color: var(--primary-font-color);
+    color: var(--primary-font-color, var(--prism-color, inherit));

31-34: LGTM on intent: minimal FOUC while token highlighting resolves

Selector scope and cascade behavior align with the goal: default line color until inline token colors apply. Non-invasive and consistent with existing theme vars.

---

31-34: Verify theme variable definitions and contrast for code blocks

• Confirm that --primary-font-color is indeed declared in src/css/theming.css for both modes (light uses var(--gray-800), dark uses rgb(247,250,252)).
• Note that --prism-background-color and --prism-color aren’t defined in our repo’s CSS—they come from the Prism theme shipped by Docusaurus. Please verify those variables are loaded at runtime.
• In your browser’s devtools (light + dark), inspect a code block’s computed background-color/color to ensure the contrast ratio meets WCAG AA.
• Finally, verify that Prism’s .token selectors (and any inline style="color:…" on <span>) still override the base > span rule as intended.
