/*
 * SimpleAIHub - Layout Polish / Small UI Fixes
 * Loaded after accessibility typography so readability and layout rules are consistent.
 *
 * Goals:
 *  - Keep code toolbar controls from overlapping.
 *  - Keep practice-card action/hint content from colliding with the description.
 *  - Give recap items clear spacing.
 *  - Keep lesson previous/next navigation as separate, readable controls.
 *  - Prevent horizontal overflow without shrinking text.
