Not worth it for this use case. +- **Alternative considered**: 2-char custom alphabet (like OmO's 256 buckets) — fewer buckets increases collision risk for identical short paragraphs. 4 hex chars are still very compact. +- **Alternative considered**: Full SHA256 — overkill, wastes tokens. + +### Hash Input: Visible text from `build_text_map()` + +- **Decision**: Hash is computed from `build_text_map(paragraph).text` — the same text the user sees. +- **Why**: This is exactly what `get_visible_text()` already uses.

The `occurrence` parameter becomes paragraph-local. +- **Why**: This is the simplest change — we already have `build_text_map(paragraph)` and `find_in_text_map()`.
