Fix GitHub Pages deployment: change trigger branch from sophomore to main

[Copilot]

Problem

The GitHub Actions workflow for deploying to GitHub Pages was failing with the error:

Branch "sophomore" is not allowed to deploy to github-pages due to environment protection rules.

This occurred because the workflow was configured to trigger on pushes to the sophomore branch, but GitHub Pages environment protection rules only permit deployments from the main branch.

Solution

Updated .github/workflows/deploy.yml to trigger deployments on pushes to the main branch instead of sophomore:

on:
  push:
    branches: [main]  # Changed from [sophomore]
  workflow_dispatch:

Impact

• Deployments will now succeed when changes are pushed to the main branch
• The workflow respects GitHub Pages environment protection rules
• Manual workflow dispatch still available via the Actions tab if needed
• No changes to the deployment process itself, only the trigger branch

This is a minimal configuration change that aligns the workflow with GitHub Pages security requirements.

Original prompt

Branch "sophomore" is not allowed to deploy to github-pages due to environment protection rules.
