/* ==========================================================================
   PULSE V2.2 — account.css · "ION ATMOSPHERE"
   account.html — rich functional page (profile / subscription / devices /
   sign-in methods / danger zone). The DOM contract of the VERBATIM v1
   account-page.js + nav-auth.js + avatar-helper.js is preserved in the
   markup; this file reskins around it. Requires tokens.css + base.css.

   The verbatim JS renders fragments via innerHTML that reference v1 token
   names with fallbacks — var(--bg-elev,#1a1a20), var(--border,#2a2a30),
   var(--text-secondary,#aaa), var(--red,#ef4444). The aliases below map
   them onto V2 tokens so JS-rendered UI follows BOTH themes instead of
   falling back to v1's hex constants.
