/* The Tools panel — what the layer brings that the agent does not have.
   ------------------------------------------------------------------
   Every other capability tab shows something the visitor already owns
   being connected, run or held. This one is the opposite: five tools
   that arrive with Askpilot and need no setup, which is the whole
   argument for a layer rather than another integration.

   Drawn as a shelf inside the layer: five rows, each with what the
   tool is and one line of what a workflow does with it. A highlight
   travels down the rows on a 15s loop, one row at a time, so it reads
   as a workflow reaching for each in turn rather than five things
   blinking. The loop is decoration only — every word is in the markup,
   so the panel is complete with CSS and JS both off. */
