Fixed

• Fixed a crash (StackOverflowError) when a One Way Glass was disguised as another One Way Glass — this could crash on placement and corrupt the world so it crashed on every load. Affected worlds now load fine.

Added

• Glass Painter Brush now works as an eyedropper. Shift + right-click any block to copy its color into the brush — works on Colored Glass (exact RGB), any block with a color tint like grass/leaves/water (vanilla and modded), and falls back to the block's map color for everything else.
• Colorable Glass Pane and Colorable Stained Glass Pane — pane versions of the colorable glass blocks. Full RGB picker, light emission, redstone signal and pass-through flags all work the same. Paint them with the Glass Painter Brush, copy colors with the eyedropper. Craft 16 panes from 6 colorable glass like a vanilla pane recipe.

Changed

• Colorable Glass and Colorable Stained Glass now show a ✨ 3D cube in the inventory, so they're easy to spot. (The placed block is still a clean white base that paints to any RGB color.)
• Clear Fluid Glass and Clear Fluid Fake Glass got distinct water-themed inventory icons.
• Colorable Glass Pane and Colorable Stained Glass Pane use matching ✨ icons.

Fixed

• One Way Glass tooltip no longer shows a literal "\n" — the description now wraps onto a second line properly.

• Added Tinted One Way Glass
• Fix: cull water faces adjacent to Clear Fluid Glass via LiquidBlockRenderer mixin
• Updated PT_BR localization (thanks PrincessStellar)
• One Way Glass faces now connect via Fusion CTM, just like the rest of the glass blocks. Works on both sides of the block, including through the opaque (mimic) face when the mimic is glass.
