Redesign the podcast landing page: topic filtering + image grid instead of a plain list

Feedback (future / nice-to-have)

"For the future — redo the podcast landing page itself. Right now it's just a list with names and links to people. It'd be great to have some filtering by topic, and to make it a grid rather than a list. I understand this keeps the Data Talks Club style — some developers have very simple sites where everything is just listed out — but it feels like people interact better with pictures."

Current behavior

The podcast landing is a plain text list of titles/links (people-centric), matching the minimalist DataTalks.Club style.

Proposed change

• Filtering by topic on the landing page.
• Card/grid layout with images/thumbnails instead of a flat list — more visual and engaging.
• Preserve the DataTalks.Club aesthetic, but lean on episode/guest imagery so items are more scannable and clickable.

Notes

• Explicitly flagged as lower priority ("for the future, not sure how relevant").
• Trade-off to weigh: the current minimalist list vs. a richer visual grid. Keep it consistent with the main-site design alignment already done.

Start by reviewing the current podcast landing page and the main-site design alignment referenced in the issue. Define how topic filtering, guest or episode imagery, and the grid should preserve the minimalist style; the work is done when the landing page supports those interactions and presents the podcast items as a visual grid.
