// Domain enums stored by **name** (never by index) via Drift `textEnum`, so
// the stored keys are stable across migrations. Per data-model §5.2, values
// may only be appended, never renumbered or reused; when sync arrives, readers
// must tolerate unknown values (map to a safe default). No sync yet in Block 1.

/// The form in which a lot is held. `seed` is dry seed (the only form
/// germination tests apply to); the rest are living/vegetative material. Values
/// are stored by name and append-only (data-model §5): never renamed/reordered.
///
/// - `seedling` — a young plant grown from seed, to transplant (plantón).
/// - `plant` — an established plant (potted or bare-root).
/// - `tree` — a woody plant: tree or shrub.
/// - `bulb` — a storage organ: bulb, corm, tuber or rhizome.
/// - `cutting` — vegetative propagation material (cutting, scion).

/// How living plant material is packaged/supplied — an optional attribute of a
/// non-seed [Lot], kept separate from the amount. Append-only by name.
///
/// - `pot` — in a pot/container (maceta/contenedor).
/// - `tray` — in a plug/cell tray (bandeja de alvéolos).
/// - `plug` — a single plug/cell.
/// - `bareRoot` — dormant, roots exposed, no soil (raíz desnuda).
/// - `rootBall` — dug with an intact soil ball (cepellón).

/// counting. Modelled on the qualitative scale a real seed bank used
/// (mucha/bastante/suficiente/poca), where each level is defined by what you
/// can do with it. Optional alternative to a precise Quantity. Append-only by
/// name.
///
/// - `plentyToShare` — surplus, free to give away (mucha).
/// - `enoughToShare` — can share a little, sparingly (bastante).

/// - `runningLow` — only enough to keep the variety alive (poca).

/// - `jarWithDesiccant` — sealed jar with a drying agent (bote con sílice).
/// - `glassJar` — plain glass jar (bote de cristal).
/// - `paperEnvelope` — paper envelope (sobre de papel).

/// - `plasticBag` — plastic bag (bolsa de plástico).
