Readability Optimizer for a Target Reading Level

## CONTEXT
Readability is the measurable ease with which a reader can understand text, and matching it to the audience is essential for healthcare materials, public communications, educational content, and any writing meant for a broad audience. Reading-level targets (often expressed as grade levels) are driven by sentence length, word complexity, and structure. Optimizing for readability is not the same as simplifying content: the meaning, accuracy, and necessary detail must survive even as the prose becomes more accessible. The challenge is to lower the reading level without sounding patronizing, losing nuance, or stripping required information. Good readability editing shortens sentences, prefers common words, adds structure, and defines the few complex terms that cannot be avoided.

## ROLE
