/* ==========================================================================
   TPRC Client Portal — admin layer

   Layer 3, sitting on top of tprc-tokens.css (values) and tprc-ui.css
   (client-portal primitives). Admin screens are denser and more table-heavy
   than the client portal, so they need their own primitives: stat tiles,
   audit tables, filter bars and a branded auth shell.

   Rules this file follows, inherited from the design handoff:
     - Never a literal colour or pixel value. Everything resolves to a --t-*
       token, so a brand change propagates here for free.
     - Orange is the single accent. It marks the primary action and active
       state, never decoration.
     - Status is never colour alone: every badge carries a text label.
     - Minimum 44px tap target on anything interactive.

   Namespaced `adm-` so it cannot collide with the client `t-` primitives or
   the legacy Bootstrap/design-system rules still loaded on these pages.

   Load order: AFTER tprc-ui.css.

/* --------------------------------------------------------------------------
   16. Admin sidebar
   The deck specifies a sticky top bar with no sidebar, but that is the client
   portal: six destinations and a single tenant. Admin has eleven destinations
   and role gating, which a horizontal bar cannot carry, so the sidebar stays
   and instead inherits the deck's restraint.

   What that means concretely:
     - The charcoal is the deck's panel charcoal, not the old blue-slate.
     - Labels are quiet by default and only the ACTIVE item gets ink and
       weight, so the eye lands on where you are rather than on the menu.
     - Active state is a 3px orange bar plus white text, the sidebar analogue
       of the deck's 2px orange tab underline. No filled orange block: the
       accent marks, it does not decorate.
     - Micro labels follow the type scale (11px / 700 / 0.08em / uppercase).

   Scoped to .sidebar-admin so the client sidebar is untouched. Dropping
   `.sidebar-admin` from these selectors would extend the same treatment to
   the whole portal.

   17. Page ground
   Admin screens were landing on three different greys: most inherited
   --bg-body (#F5F6FA), pages still carrying .dashboard-page got #F8FAFC, and
   the client shell used the deck's wash. They all share one ground now.

   background-attachment: fixed matches body.t-shell. The background
   propagates from <body> to the canvas (the root is deliberately transparent,
   see css/styles.css), and a propagated gradient would otherwise stretch over
   the whole document — several thousand pixels on a long page — leaving the
   visible area looking flat and shifting as you scroll. Fixed maps it to the
   viewport so the ground reads the same at any scroll position.
