Vertical slabs and mixed slabs for modern Minecraft.

Features
- Vertical slabs that just work — no new recipes or crafting steps. - Mixed slabs: two different slabs in one block space, with per-half breaking (KleeSlabs-style). - Single codebase for both loaders through Architectury. - Additional compatibility added for Mo Glass and Blockus. > Note: Mo Glass slabs cannot be mixed.

How it plays
- Controls → Key Binds → Full Slabs → Toggle Overlay cycle between three placement modes to control how halves place. Bind in Controls → Key Binds → Full Slabs → Toggle Overlay. - Controls → Key Binds → Full Slabs → Toggle Overlay a lightweight overlay shows which halves will be placed or broken. Bind in Controls → Key Binds → Full Slabs → Toggle Overlay.
If you’ve used “vertical slab only” mods before, Full Slabs maintains that simplicity and adds mixing and interaction affordances on top, without recipe clutter.
