v0.27.1 — drag the menu anywhere + upward flip + ModKit settings bridge

Added — drag the whole menu anywhere on the screen (⋮⋮ grip)

• The overlay could only sit in one of two corners, and the anchor dropdown only swaps between them — which is no help when another mod parks its own menu bar in both. The collapsed header now starts with a ⋮⋮ grip: drag it to move the entire overlay (dropdown row + hover preview + tab panel) as one unit; double-click resets it to the anchored corner. Tooltip localized in all 16 languages (overlay_drag_tooltip).
• The drag is a screen-space delta on top of the anchor, not a new positioning mode: every group is still anchored to its corner (Left/Right from the settings dropdown) and the same (dx, dy) is added to both horizontal offsets, which translates a right-anchored control — whose base offsets are negative — by exactly the same pixels as a left-anchored one. So one offset serves both anchors and the existing layout code is untouched apart from the + _dragOffset term.
• Drag continues after the cursor slides off the grip. _GuiInput only fires while the pointer is inside the control, so it just starts/stops the drag; the motion itself is carried in _Input, which runs ahead of GUI routing. Without that split a fast drag "slips off" the handle and the menu stops following the mouse.
• Persisted to its own file (overlay_layout.json, next to skin_choices.json) rather than into skin_choices.json. That file is watched by ChoicesFileWatcher and any write to it pops the restart/countdown modal — moving a menu must not look like a skin change. Saved on drag end only, not per motion frame.
• The offset is clamped so the menu can never be lost off-screen: at least a 180 px horizontal sliver of the header stays visible, and vertically whichever element is lowest is kept on-screen. The clamp is re-applied once on attach, because a position saved at one resolution can land off-screen at another.

Added — the panel opens upward when the menu is dragged into the bottom half

• Dragging the header below the screen's vertical midpoint would have made the expanded body grow straight off the bottom edge. Past that midpoint the accordion flips: the body is moved to be the first child and the group switches to bottom-anchored with GrowVertical.Begin, so it grows up from the header — and the dropdown row mirrors to just below the header. The header itself never moves, so the flip is invisible while collapsed.
• Child reordering (MoveChild) is the flip's only structural side effect and lives in one place (ApplyAccordionOrder), called both on the flip transition and once after the header row and body are built — the early call from PositionAccordion short-circuits while those children don't exist yet.

Changed — settings registration moved to the shared ModKit bridge

• ModConfigBridge was ~110 lines of hand-rolled reflection against ModConfig.ModConfigApi. It now delegates to Sts2.ModKit.Config.ModConfigBridge, which registers through either RitsuLib or ModConfig (RitsuLib preferred) and no-ops with defaults when neither is installed — so the mod still has zero hard dependency, and users with only RitsuLib now get the overlay-position dropdown too. The local class name is kept so MainFile's call site is unchanged.
• The build moved to Sts2.ModKit.props (shared references / publicizer / mods-folder copy), and an AssemblyResolverBootstrap module initializer registers the AssemblyLoadContext.Resolving hook the ModKit consumers need. Build note: the project now imports ..\Sts2.ModKit\build\Sts2.ModKit.props, so building from a standalone clone of this repository requires the sibling Sts2.ModKit directory.

Verification

• Release build clean and shipped to the Steam Workshop as 0.27.1 (item 3747513223). Both the drag/flip geometry and the clamp are analytic — computed from the anchors' base offsets and the viewport size rather than measured from the tree — so they hold at any resolution without a layout pass; in-game confirmation of the flip at low resolutions is still worth a look.

Install (manual)

Extract Sts2SkinManager/ from the attached zip into <Slay the Spire 2>/mods/. The zip now ships two DLLs — Sts2SkinManager.dll and Sts2.ModKit.dll (the shared library the settings bridge loads); keep both side by side. Steam Workshop subscribers get the same build automatically as item 3747513223.
