   PWA install UI, offline page, and standalone-shell polish.
   Loaded AFTER portal.css, so every --token below is already defined.
   Strict-CSP friendly: external file only, no inline anything.

   Scope note: this is the PWA core (phase 1). Per-page mobile refinement
   (tables/forms across dashboard, projects, invoices, …) is the phase-2 pass.
