Replace duplicate .count calls with cached variables using .size method. This reduces database queries by approximately 50% on mobile board views. Changes: - Cache card counts in local variables (postponed, awaiting_triage, closed, active) - Use .size instead of .count (more intelligent - leverages preload when available) - Reuse cached values instead of making duplicate SQL queries Impact: - Mobile columns view: reduced from ~6 to ~3 COUNT queries - Better performance with no visual changes to the UI
