/* ==========================================================================
   quizvie-responsive-learning.css
   Mobile/tablet responsive overrides for the LM/FM learning & authoring
   screens (makers, tests, study, results, similar-question, embedded).

   - Loaded LAST on every page, after the page's own stylesheet, so
     equal-specificity rules here win by cascade. !important is used only
     where JS/inline sizing or later duplicated page rules must be beaten.
   - Every rule lives inside a max-width media query: desktop (>=1024px)
     is completely untouched.
   - This file is linked from every page of the app, so selectors are
     scoped to learning-screen structures (.FM-maker, .LM__maker,
     .result-view, .player-section, .OMR-cell, ...).

   Breakpoints:
     <=1023px  tablets and below (768px tablets included)
     <=767px   phones (360 / 375 / 390 / 430)
     <=480px   small phones fine-tuning
     landscape phones: (orientation: landscape) and (max-height: 520px)
