/* ============================================================================
   SKYROCK LOGBOOKS — THE GUIDE (/guide/Logbooks · public/guides/logbooks/)
   ----------------------------------------------------------------------------
   The teaching counterpart of the landing (logbooks-landing/styles.css), and a
   member of the same family: the cosmos brackets ONE white sheet, and the sheet
   speaks the product's own visual language. Tokens MIRROR the landing's — which
   themselves mirror components/logbooks/logbooks.css and its measured ink
   ladder (contrast ratios recorded there). Do not re-pick these by eye.

   What is new here relative to the landing: the guide draws MANY exhibits of
   the real builder (module cards, ports, cables, the health strip), so the
   canvas vocabulary lives here as reusable SVG classes (.gd-mod-*, .gd-port*,
   .gd-cable*) whose values come from the app stylesheet verbatim: 22px dot
   paper, 2.25px navy value cables, gold out-ports, the marked base port, the
   gate stitch (dash 4 5 in dark gold-ink), the error red #b3261e/#c6362c.
   The canvas exhibits are drawn BOTTOM-TO-TOP like the real workspace.
