Parse line-by-line. - **Pretty** (`pretty: true`): Multi-line indented JSON per event. Parse by reading the entire file and splitting on top-level objects (e.g. `JSON.parse('[' + content.replace(/\}\n\{/g, '},{') + ']')`) or use a streaming JSON parser. Always check the first few bytes of the file to detect the format: if the second character is a newline or `"`, it's NDJSON; if it's a space or newline followed by spaces, it's pretty-printed. **Search order** — check these locations relative to the project root: 1. `.evlog/logs/` (default) 2.
