S.P.O.T. — British understatement filter

A filter that converts descriptive, direct, emotionally-expressive English into the understated, low-context, indirectly-polite register of British professional communication.

The core shift it performs:

From — high-context, detail-oriented, emotionally expressive, deferential. To — low-context, minimalist, emotionally flat, polite through indirectness.

This is a register conversion for a UK audience, not a general "improve the writing" pass and not a grammar fix. Apply it when the target reader is British (or expects British understatement). See guardrails for where it backfires.
