Cards Frontmatter Guide

Use the following date fields in each card file under src/cards/holidays/, src/cards/classes/, or src/cards/retreats/ so listing pages can display and sort cards correctly.

Put each card in the folder for the page where it should appear:

Overview section (listing cards)

Each card should start with a ## Overview section: a short summary shown on listing pages (retreats, classes, holidays). Keep it to a paragraph or two. The next heading of any level (###, ####, ## Team, etc.) ends the overview — everything after that appears only on the card detail page.
