/* ============================================================================
 * readability-boost.css —— 全站可读性提升（2026-10-23 用户令）
 * ----------------------------------------------------------------------------
 * 用户诉求：学员反馈「字体太小」。
 * 处理原则（按容器余量分两类，不搞一刀切）：
 *   ① 容器/按钮本身够大（有留白、min-height 富余）→ 只放大字号，不动盒子；
 *   ② 容器/按钮也小（文字贴边、高度只有 30px 上下）→ 字号与盒子一起放大。
 *
 * 字号阶梯（按原值分档，避免大小字挤在一起）：
 *   原 9-10px → 13px    原 11px → 13.5px    原 12px → 14px
 *   表格类密度高，只到 13px（再大会横向溢出）。
 *
 * 只改字号与必要的盒子尺寸；不改配色、不改栅格、不改交互。
 * 加载位置：index.html 最后一个 <link>（同选择器靠后覆盖，无需 !important）。
 * ⚠ 学习面 #stage1（固定 1180×500 画布）不在本文件范围 —— 那里放大字号会
 *   撑出画布，需按 learning-surface-fit 的缩放规则单独评估。
