/*
 * MasterStudy LMS (free plugin, wordpress.org slug
 * masterstudy-lms-learning-management-system; the handoff doc specs
 * MasterStudy LMS Pro for production, same markup/classes for styling
 * purposes) compatibility overrides.
 *
 * CSS-only for everything below, on purpose: MasterStudy's own support team
 * has publicly confirmed their front-end architecture uses hardcoded
 * dimensions in places and isn't guaranteed stable across versions. A CSS
 * selector that stops matching after an update degrades silently (section
 * looks slightly off-brand); a stale PHP template override can outright
 * break a page. Prefer adding a selector here.
 *
 * Because this is now a real active theme (not a plugin), MasterStudy's
 * `locate_template()`-based override mechanism works natively: dropping a
 * file at stm-lms-templates/<same-subpath>.php in this theme's root
 * overrides that MasterStudy template automatically — see
 * stm-lms-templates/README.md before reaching for that, though; CSS should
 * still be the default tool.
 *
 * Class names verified against the shipped MasterStudy LMS v3.7.37 source
 * (assets/css + _core/lms/**\/*.php templates), current as of this file's
 * writing. If MasterStudy renames a class in a future version, these rules
 * just stop matching — they degrade silently, not destructively.
 *
 * Confidence note: `.ms_lms_courses_card_item*` selectors are a best-effort
 * fallback for the Elementor "Courses" widget, which uses a different markup
 * layer than the core shortcode/template grid. Verify against the actual
 * site if that widget is used (the handoff doc's stack uses Elementor for
 * landing/marketing pages, so this is a realistic path).
