The preceding commits taught the import worker to coerce custom CSV column values into JSON booleans and numbers via `coerceCustomValue` in `apps/api/src/jobs/import-processor.ts`. Without a corresponding docs update, users can't predict whether a cell like `01234` lands as a string or as the number `1234`, or which segment-filter operators a field will expose after import. Add two bullets to the existing "Rules and limits" list in the contact-import guide, adjacent to the **Date columns** bullet that already documents value typing for ISO 8601 dates. The bullets mirror that style and brevity: one names the boolean keyword set and the toggle it unlocks in segment filters, the other names the numeric pattern, the `gt`/`lt` operators it unlocks, and the deliberately preserved-as-string forms (leading zeros, `+`-prefixed, scientific notation) so users keep their IDs, zip codes, and phone numbers intact. No other content is touched. Closes the documentation gap for useplunk/plunk#390. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
