/**
 * OpenThink SAS — Bootstrap 5 (Tabler) overrides
 *
 * This file ensures Tabler/BS5 styles co-exist with legacy Bootstrap 2.x
 * classes that are still present in un-migrated templates.
 *
 * Strategy:
 * - Namespace modern styles under .ots-modern or body.ots-modern
 * - Legacy classes (.row-fluid, .span*, .btn-navbar, etc.) remain untouched
 * - Only activate BS5 overrides inside .ots-modern context
