   (wwwroot/css/tenant-plus-loader.css)
   -----------------------------------------------------------------------------
   Tenant+ branded post-sign-in loader.

   When a user signs into Tenant+ via the modal (tenant-plus-signin.js), the
   redirect into /tenant-portal/... used to flash the generic Ikhayalami
   loader. That loader was right for the marketing site but wrong for a
   premium ops dashboard.

   This is the Tenant+ version:
     • Charcoal canvas (same #14141A as the sidebar) so it visually pre-rolls
       into the dashboard chrome.
     • Orange + sky-blue gradient ring (brand colours from the existing
       palette — no new tokens introduced).
     • A pulsing "+" glyph at the center — the brand mark used in the
       sidebar, header chip, and burger drawer card.
     • Stacked status messages that cycle while the page loads.
     • A bottom progress bar with the same gradient.

   Self-contained — namespaced under .tpl- so it can co-exist with the
   generic site loader on shared pages.
