/* ============================================================================
 * TraPay — legacy-content shim
 *
 * The CMS imported ~1500 legacy posts + landings whose body HTML was authored
 * against Bootstrap 3 and the old TraPay theme. The new theme doesn't ship
 * Bootstrap, so those classes were rendering bare. This file makes the legacy
 * markup look right without polluting the new theme.
 *
 * SCOPE: everything below is intentionally scoped to `.prose` so it only fires
 *        inside CMS-rendered body content (page/post/landing body), never the
 *        new-theme chrome. Keep new selectors under `.prose` too.
 *
 * Sections:
 *   1. Bootstrap 3 grid (.row / .col-*) — fluid 12-col flexbox, mobile first
 *   2. Bootstrap 3 utilities (img-responsive / pull-* / center-block / text-*)
 *   3. Bootstrap 3 buttons (.btn / .btn-warning / .btn-link)
 *   4. Bootstrap 3 panels + accordion (.panel-group / .collapse — FAQ blocks)
 *   5. Bootstrap 3 tables (.table / .table-bordered / .table-striped / .table-responsive)
 *   6. Bootstrap 3 alerts/wells
 *   7. Legacy custom (.ibox / .ibox2 / .sign / .well)
 *   8. Image alignment (img.pull-left / img.pull-right) — RTL aware
 *
 * RTL: body is rtl, so float:left/right are visual-LEFT/visual-RIGHT (per
 *       CSS spec — `float` is physical, not logical). This matches the
 *       legacy author intent which was also rtl.

 * TraPay — modernized-body base spacing (optimize-post / fix-landing output)

 * WHY: improved post/landing bodies live in the DB and use Tailwind utility
 * classes (my-6, mt-4, p-8, space-y-*). Tailwind PURGES unused classes by
 * scanning source files — it never sees DB body HTML — so those utilities
 * silently produce NO CSS and every element collapses to margin:0 (cramped,
 * no rhythm). `.tp-modernized-body` also intentionally drops `.prose`, so
 * there is no fallback typographic spacing either.
 *
 * FIX: give the scope real, compiled base spacing here. Element selectors only
 * (no Tailwind class names) so it works regardless of which utilities the body
 * HTML carries. Mirrors the 8pt rhythm in DESIGN-SYSTEM.md.
