/* Layout: a bound drawing set. Each section is one sheet with a zoned border and a sheet tab;
   drafting line weights (hairline, medium, heavy) carry the hierarchy instead of cards and shadows.
   The set index: the cover sheet of coletebou.github.io, set in the plan set's own faces (Barlow
   Condensed and B612, SIL OFL, served from this site), so no font service is asked for anything. */
