/* =============================================================================
   PTAC Event Posts Grid — [ptac_event_posts] shortcode
   Design system: aligned with .ptac-tl-card (Technical Library) and the
   Eventbrite (.wfea) card aesthetic in ptac-events.css.

   Depends on technical-library.css being loaded first (enqueued as a
   dependency). Filter bar reuses .ptac-tl-field / .ptac-tl-btn classes.
   Pagination reuses .ptac-tl-pagination classes.

   Custom properties:
     --ptac-ev-teal:   var(--ast-global-color-0, #1b5e61)
     --ptac-ev-dark:   #0f2d2f
     --ptac-ev-body:   #3d4a4c
     --ptac-ev-muted:  rgba(27, 94, 97, 0.85)
     --ptac-ev-border: rgba(27, 94, 97, 0.12)
     --ptac-ev-surface:rgba(27, 94, 97, 0.05)
