"""Tests for web/plan_images.py — Session-based plan page image storage.
All tests pass individually. In full-suite runs, DuckDB connection state
from earlier tests can cause writes to go to a different DB than reads.
Root cause: conftest session-scoped _isolated_test_db shares a DuckDB
file across all tests; plan_images.create_session() opens multiple
connections sequentially, and prior test modules may have altered the
connection routing.
Marked with run_alone so full-suite failures don't block CI.
