v3.2.17

Internal: post-ship verification hardening (no user-facing change)

The v3.2.16 combo-bleed fix is correct and shipped — this release only hardens the code and test around it after a verification swarm (6 topic agents, Sonnet + Opus, plus an orchestrator-side /code-review) flagged two latent issues. The binary behaves identically to v3.2.16; this exists to keep main and the published release in lockstep.

• Killed a silent-skip path. The two click-action combos were typed ComboBox, and Load read their OverflowBelow behind an is ThemedComboBox cast — if a future edit ever built one as a plain ComboBox, the overflow reservation would be silently skipped and the bleed would return undetected. The fields are now typed ThemedComboBox, so the cast is gone and a type change fails to compile (loud by construction).
• Made the regression test non-vacuous. The new v3.2.16 combo guard asserted Margin.Bottom > 2, but the breathing-room term (LogicalToDeviceUnits(4)) alone cleared that threshold — so the test would have passed even if the load-bearing OverflowBelow reservation were dropped. It now asserts OverflowBelow > 0 and Margin.Bottom > (baseline + breathing), deriving both inputs from live control state and a shared ClickComboBottomBreathingPx constant rather than hardcoded literals that could drift from the implementation.

What's underneath

• SyncthingPause/SettingsForm.cs — _cboDblClick / _cboMiddleClick retyped ComboBox → ThemedComboBox (cast removed in Load); breathing-room literal 4 promoted to the named ClickComboBottomBreathingPx constant.
• SyncthingPause.Tests/DpiLayoutRegressionTests.cs — combo guard tightened to prove the OverflowBelow term is actually reserved; threshold derived from Margin.Top + the shared constant.
• SyncthingPause.csproj — 3.2.16 → 3.2.17.
