Summary

This PR modernizes the Quarkus Insights page (/insights) by converting the archived episodes section from a card grid into a structured, responsive 4-column table. It also decouples episode numbers and titles into explicit schema fields across _data/insights-videos.yaml and updates the automated weekly archive workflow to preserve this format.

Key Changes

• Archived Episodes Table (templates/partials/insights-videos.html):

  • Replaced the .card grid with a standard table.tableblock wrapped in .table-responsive.
  • Added 4 clear columns: Episode, Title (linked to YouTube), Guest(s), and Streaming Date.
  • Maintained upcoming / scheduled sessions as .card-static cards with clean {=...} interpolation syntax.

• Explicit Metadata Migration (_data/insights-videos.yaml):

  • Separated episode: <number> and title: "<clean title>" across all 260+ past and upcoming entries.
  • Preserved special non-episode entries (e.g. holiday breaks) cleanly without episode numbers.

• Automation Sync (.github/workflows/update-insights.yml):

  • Updated the weekly archive workflow to extract episode numbers and clean titles separately when shifting upcoming sessions to pastvideos.

• Test Coverage (src/test/java/io/quarkusio/InsightsPageTest.java):

  • Added insightsPageHasArchivedEpisodesTable() to validate the 4 table headers, row visibility, and episode formatting.
  • Verified scheduled cards properly interpolate episode numbers without literal template tags.

Verification

• Ran ./mvnw test -Dtest=InsightsPageTest with all Playwright browser tests passing.
• Verified visual layout and responsiveness of both scheduled cards and the archived table in local development mode.
