Task: Merge {partial_count} partial document **full writing style** extracts into one coherent guide for {source_lang_name} → {target_lang} ({prompt_target_phrase}).

Deduplicate overlapping rules. Prefer the most specific wording. Do **not** merge terminology or glossaries (handled separately).

{writing_style_target_note}

When merging partials, EXPAND the writing-style content — do not shorten it. The merged guide should be at least {style_writing_min_bullets_full} bullets and ~3,500+ characters.

OUTPUT: Plain text only — merged full writing style guide. No markers, no preamble, no code fences. ≤8,000 characters.
