/**
 * Ei-curated effective limits for known models.
 *
 * These are NOT the provider's advertised maximums — they're the limits Ei uses in practice.
 * For example, Haiku's advertised context is 200k but real-world extraction quality degrades
 * above ~100k, so we cap it there. When adding new models, prefer conservative values based
 * on actual usage over marketing specs.
 *
 * Consumed two ways:
 * - Creation time (`tui/src/util/provider-detection.ts` `buildProviderAccounts`): stamps these
 *   values onto a freshly-detected ModelConfig as a starting point.
 * - Call time (`llm-client.ts` `callLLMRaw`): used as a fallback default whenever the stored
 *   ModelConfig doesn't have an explicit value — so a value dropped or never set on the stored
 *   config (e.g. a hand-edited or renamed model entry) still resolves correctly. An explicit
 *   field on the ModelConfig always wins over this table.
