// Reports visible elements that still carry core Redmine shapes the theme should have replaced:
// 1-3px corners (core uses 3px, M3 uses 4/8/12/16/28px or full), core's grey box shadow
// (rgba of --oc-gray-9, theme shadows never use it), square boxes outlined on all four sides
// (core's card style, e.g. the old .mypage-box), and dashed or dotted borders.
// Checks desktop and mobile, because core's responsive.css brings its own shapes. Exits 1 on any hit.
// Usage: node check-core-leaks.mjs [--verbose]
