Hwaro::Assets::Sass::NamespacedEvalError
Inherits Hwaro::Assets::Sass::SoftEvalError < Exception < Reference < Object
A failure inside a NAMESPACED reference (math.div(…), $map.key,
i.e. anything reached through an @use namespace).
These must NOT take the lenient verbatim fallback. Falling back
reconstructs the call as math.div(1px, 0) and splices that straight
into the stylesheet — but no CSS function name may contain a ., so
the result is guaranteed-invalid CSS that no browser will apply. The
author gets a silently broken declaration instead of a build error,
which is the opposite of what leniency is for (leniency exists so
valid CSS the compiler doesn't model — -webkit-…(), progid:… —
survives untouched; those are never namespaced).
