Diamond fork-joins

Section titled “Diamond fork-joins”

Stations that a line passes straight through - splitting to parallel paths and immediately rejoining - now render as flat diamond bubbles rather than a pair of overlapping pills. Common at QC branch points where multiple tools run in parallel before merging back.

Multiple file icons per station

Section titled “Multiple file icons per station”

A single station can carry more than one file icon:

Configurable section spacing

Section titled “Configurable section spacing”

--x-spacing and --y-spacing (and %%metro x_spacing: / %%metro y_spacing:) now accept any value above safe minimums rather than a small fixed set of presets.

Other improvements

Section titled “Other improvements”
  • Animated balls reduced to 1 per track (was 3)
  • Dark-mode CSS fix for transparent-background SVGs
  • TB section exit port now mirrors the entry-side gap
  • Exit/entry port pairs snapped toward downstream stations
  • Straight-through diamond fork-joins
  • Terminus stations nudged away from passing lines
  • Fork/join bubbles widened for labels; labels flip away from exit ports
  • Bypass gap2 vertical offset avoids overlap with L-shape routes
  • Stations shifted away from perpendicular entry ports
  • Exit gap now only applies to single-layer sections
