Fix hero section theme persistence issue

[Copilot]

Issue

Users who selected the dark theme when building their site reported that the hero section appeared all white after being hosted for a week.

Root Cause

When exporting a site, if the user selected a theme color in the UI but the JSON data still had "primaryColor": null, the client-side code wasn't properly defaulting to "indigo" after the site had been hosted for some time.

Changes

1. Modified the encode function in packages/mytemplate/src/types/Data.res to always write the actual color value instead of null:

   • Changed from ("primaryColor", nullable(string, t.primaryColorString)) to ("primaryColor", string(primaryColor(t)))
   • This ensures the exported JSON always contains either the user's selected color or "indigo" as the default
   • Fixes the root cause by preventing null values in the exported data

2. Updated the CDN references from version 0.7 to @latest in src/utils/Config.res:

   -    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/mytemplate.xyz@0.7/build/index.css"/>
   -    <script src="https://cdn.jsdelivr.net/npm/mytemplate.xyz@0.7/build/index.js"></script>
   +    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/mytemplate.xyz@latest/build/index.css"/>
   +    <script src="https://cdn.jsdelivr.net/npm/mytemplate.xyz@latest/build/index.js"></script>

These changes ensure theme persistence by making the color selection explicit in the exported HTML data rather than relying on client-side defaults.

Fixes #69.

@copilot do you want to try building it again from scratch

I've rebuilt the fix from scratch with a cleaner approach (commit 853fe4e).

Key changes:

1. Simplified solution: Instead of parsing and manipulating JSON at export time, I modified the encode function in Data.res to always write the actual color value (defaulting to "indigo" when not set) rather than writing null
2. Updated CDN version: Changed from @0.7 to @latest to ensure sites use the most recent client-side code
3. Removed unnecessary complexity: Eliminated the ensurePrimaryColor function and package-lock.json that were added in the previous attempt

This approach is cleaner because it fixes the root cause - ensuring the exported JSON never contains "primaryColor": null - rather than trying to patch it during export.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.jsdelivr.net
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
