What and why

Plates, nested plates and split panels already show where one section of the dock ends and the next begins, so the divider lines only repeat that. This adds a Hidden divider style: no line, and the sections keep the ordinary gap between them.

How

• dividerStyle: "none", shown as "Hidden" among the Divider style options. Config parsing accepts it, RowDivider draws no line, and PresetThumb and the settings search know it. The length, height, width and opacity rows hide while it is chosen.
• No holes. Kept at its normal width, a hidden divider left its slot plus two row gaps between the sections, wider than any gap between tiles. With Hidden (and no split) separatorWidth is -gapWidth: the divider leaves the Row (RowDivider only shows with width) and cancels its spacing in the geometry sums (slotHomeCenter, the row width, the fit's separatorWidthAt). The sections meet one ordinary gap apart.
• The change in Dock.qml is in place: its line count does not change.

Verification

• node --check of the model files and node --test tests/unit/*.test.mjs tests/unit/*.test.js (252 pass)
• python3 -m unittest discover -s tests/unit -p 'test_*.py'
• qmllint (no new error kinds)
• security-grep.py, structure-check.py, shaders-in-sync.sh
• ./tests/manifest-check.sh . and omarchy plugin validate .
• ./tests/smoke-test.sh against a running dock
• Live: lines vs Hidden on the dock (screenshot above); with Hidden the gap between sections equals the gap between tiles.

Thank you @priard — merged into v4.7.0! The -gapWidth cancellation that makes Hidden sections meet exactly one gap apart (instead of slot + two row gaps) is the kind of geometry arithmetic this dock lives on, and keeping it line-neutral in Dock.qml under the ratchet made integration clean. Verified on experimental: 254 Node + 116 Python tests, qmllint 0 errors, structure-check PASSED.
