/* AI mix-in: inline spans for dual human/AI consumption.
   Renders as monospace accent text with a subtle mechanical feel —
   a "link for AI" that humans see as a trace of structure.

   Basic:       <span class="m">ruach-memory</span>
   Typed:       <span class="m" data-kind="tool">chub_search</span>
   Dimensional: <span class="m" data-dim="count" data-unit="tool" data-value="271">271 tools</span>

   Extends naturally to middah dimensional analysis — every apparent
   scalar in prose can carry its BND type via data-dim/data-unit.
   No number is truly dimensionless. */
