/**
 * MeedSphere Academy — shared stylesheet (PR1: academy-shared-styles).
 *
 * Extracted from per-page duplicated inline <style> blocks. The reset and
 * design tokens below were byte-identical (or a safe superset with no
 * conflicting values) across every page, so they are declared once at the
 * top level.
 *
 * Everything else is scoped under a body page-class (`academy-catalog`,
 * `academy-course`, ...) because several identically-named selectors carry
 * DIFFERENT values per page — e.g. `.nav-inner` max-width is 1100px on
 * catalog/course/bundle/my-courses/index but 1280px on lesson; `main`
 * max-width/padding and `.page-title` font-size also differ per page. A
 * flat union of these rules would silently clobber one page's layout with
 * another's, so each page's original rules are preserved verbatim, scoped
 * under its own body page-class. This file is a pure extraction: zero
 * visual change from the pre-extraction inline blocks.
 *
 * Batch A: catalog, course, lesson, my-courses.
 * Batch B (appended below): index, bundle, login, register, purchases.
 * All 9 public Academy pages are now migrated onto this single stylesheet.
 *
 * PR2 (academy-visual-redesign, appended below the PR1 blocks): a
 * stylesheet-only pass evolving the card-grid density, layout rhythm, and
 * progress-indicator clarity — general "modern LMS card-grid UI" patterns
 * (denser grids, clearer progress bars, tighter type rhythm), not copied
 * from any third-party product. No markup or PHP logic was touched; every
 * value here rides the same page-scoped selectors PR1 already established.
