Constant Summary collapse

VERSION =

Versioned INDEPENDENTLY of both the ‘sasso` gem and the `sasso` crate. The gemspec pins the engine gem with a range (sasso >= 0.1.1, < 1), so a compiler bump does not force a lockstep release of this integration gem.

"0.1.1"

  false
end

.style_for(configured) ⇒ Object

Default to compressed CSS in production (smaller payload), expanded elsewhere (readable). An explicit ‘config.sasso.style` always wins.

If the asset pipeline has its own CSS compressor (a Sprockets app that set config.assets.css_compressor), stay :expanded and let the pipeline compress, avoiding wasteful double-minification. Propshaft sets no compressor, so production stays :compressed on the default Rails 8 path.
