AI Analysis
●●SolidBig BrainNiche Gem
Targets current dart-sass 1.101 while grass is stuck on 1.54.3 from 2022.
Strengths
- •13,896/13,896 sass-spec tests passing with zero failures tracked as ratchet
- •Zero runtime dependencies makes it sandbox-friendly and wasm-deployable
- •Modern color model preserves author spelling with fractional channel support
Weaknesses
- •SCSS compilers are a solved category with dart-sass and grass already established
- •v0.x status means real-world breadth beyond spec tests still needs hardening
Category
