/* ─────────────────────────────────────────────────────────────────────────
   KrasoftReport — landing page (Index.cshtml)

   Dark, sophisticated design positioned as "companion service for Krasoft
   Platform". Heavy use of layered gradients, glass surfaces, scroll-driven
   reveals. Self-contained — no external font/icon deps beyond the Inter
   load in site.css.

   All class names are prefixed with `lp-` (landing page) so they don't
   collide with the DevExpress widgets, the file manager (`fm-*`), or the
   generic site.css selectors (`.btn`, `.container`, `.footer`).

   The .footer + body dark overrides ARE scoped to Index.cshtml (the page's
   own @section Styles block sets body/footer background), so Reports,
   ViewDashboard, ViewReport, FileManagerSoft, etc. stay light.
