/* =============================================================================
   Visitor Assistance — Command Center integration
   =============================================================================

   DESIGN RATIONALE (every choice here has a reason; none of it is ornament):

   The Office of the Secretary of the Sanggunian IS a records cabinet. So the
   3D in this block is the metaphor made literal, not a gradient effect bolted
   on top:

   · The tabs are physical FOLDER TABS. The active one is raised on the Z axis
     and its bottom border is erased so it visually fuses with the panel below
     — exactly how a card sticks out of a drawer. Inactive tabs sit recessed
     and desaturated, as if pushed back into the file.
   · The heading is ENGRAVED BRASS. Layered shadows extrude the letterform the
     way the plaques on a Philippine city hall are cast — gold on navy, lit
     from top-left. It is the same gold already in the SP palette, so it reads
     as this institution rather than as a web trend.
   · Buttons have a real UNDERSIDE. Pressing collapses the shadow and drops the
     face by exactly that distance, so the travel is physically honest.

   Everything degrades: no 3D under prefers-reduced-motion, no colour-only
   status anywhere, and the whole block still works with JS disabled.

   Depends on the tokens already defined in sppag-command-center.css
   (--sp-navy, --sp-gold, --sp-blue …). It adds NO new palette.
