   legacy-bridge — reroutes the site-wide /css/style.css design system
   --------------------------------------------------------------------------
   healtharea/patientarea/hospitalarea's area.php still loads /css/style.css
   on every page (it predates the shell and still supplies some page-content
   rules, per that file's own docblock). That stylesheet owns its own
   accent, bg, text, success, warning, danger, and glass custom-property token set
   (a blue "Design System v3" palette), which generic Bootstrap-ish classes
   used in page content (.btn-primary, .alert-info, .nav-tabs, etc.) read
   from — so without this bridge, those elements render in the old blue
   palette inside an otherwise-Meridian shell.

   Overriding the same custom-property names here, scoped to body.lx (which
   wraps every LX-shell page), re-points every one of style.css's colour
   tokens — and everything derived from them via its own "legacy aliases" and
   "pricing token aliases" blocks — at Meridian's tokens. This works
   regardless of stylesheet load order: body.lx is a closer ancestor than
   :root for anything inside the shell, so its values always win for
   properties that are read by descendants of body.lx.

   Excludes body.lx-lite (public.php/auth.php's marketing and login pages):
   those carry their own, more targeted bridge (marketing.css/auth.css) with
   a few deliberate, mode-invariant departures from this one — most
   critically --bg-footer, which marketing.css hardcodes to a literal dark
   colour because #site-footer's white text is mode-invariant by design.
   Without this exclusion, body.lx's closer proximity to #site-footer than
   :root made this file's own (mode-reactive, cream-in-light-mode)
   --bg-footer win instead, silently breaking that contrast in light mode. */

  /* ── Orphaned surface tokens ───────────────────────────────────────────────
     These names are referenced by per-page and per-widget CSS carried over
     from the pre-shell dark theme, but were never defined anywhere — the
     stylesheet that owned them is gone. Each therefore resolved to its
     hardcoded dark fallback (#1a1a2e, #1a1f2e, rgba(255,255,255,0.03)…), or,
     where the author wrote no fallback, to nothing at all — an invalid value,
     so the element rendered with no surface whatsoever. Either way the card
     lost its glass. Defining them here restores the intended surface without
     touching the ~40 call sites. */
