/* registry: Platform A, first block. Gene and rule registry: a GRCh38 chromosome map built from the published site sets,
   one hashed rule-table button per gene, a zoom into the selected gene's sites, and the control column.
   Shared components (figbox, ctl, readout, opts, key, tags) are used as they are; this file lays out the map and marks only.
   v5 (the films' look): warm-grey chromosome cells, ink pins with hairline leaders to the rule-table labels (Figtree caps, the films'
   labels), the selected table framed in orange like the films' "32 bytes" box, site marks with a fine ink outline. */
