+-- Migration 028: drop banner_path from theses and v_theses_full.
+--
+-- 027_drop_banner_path failed because v_theses_full references banner_path.
+-- This migration:
+--   1. Drops dependent views
+--   2. Drops the column
+--   3. Recreates the view without banner_path
+-- Safe to re-run (views are re-created fresh each time, column drop is idempotent via error skip).
+
+-- Drop dependent views first (v_theses_public depends on v_theses_full)
+DROP VIEW IF EXISTS v_theses_public;
+DROP VIEW IF EXISTS v_theses_full;
+
+-- Drop column (may fail if already absent → run.php skips that error)
+ALTER TABLE theses DROP COLUMN banner_path;
+
+-- Recreate v_theses_full without banner_path
