// Package fejkdata generates fake data from recursive JSON templates.
//
// Data lives in JSON, not in Go. A generator starts from the shipped data set and
// layers any directories you add; folders and files become a dot-path namespace,
// then generate values by path:
//
// f, _ := fejkdata.New(fejkdata.WithSeed(42))
// f.Fake("sv_SE.address") // "Räfsalsvägen 43\n442 42 Kungälv"
// f.Fake("sv_SE.address.locality") // "Umeå": a second call draws afresh
//
// Several sources merge in order, the last winning a name clash, so custom data
// layers over the built-ins. The JSON template format is documented in the [README].

package fejkdata
// Vocabulary
//
// - draw — one pick from a choice, or one row taken from a table: `pick`,
// `resolveChoice`, `renderScope.drawRowOf`. Every {…} draws afresh, bar a read of a name.
// - expansion — one render of one format: `expand`.
// - render — one walk of the tree from an entry point, over one `frameStack`:
// `Generator.Fake`, `FakeRecord`, `Template.Fake` and `RecordTemplate.Fake`
// start one each, and `FakeStruct` one per record.
// - named pick — the draw a token such as {/person as p} binds to a name, drawn
// on its first read and kept while its scope renders: a category, or one
// repeat iteration: `nameBinding`, `nameScope`, `namedPick`, `pickFrame`.
// - memo — what a named pick keeps its draws in, the variant drawn at each level
// and the value each path read: `drawMemo`.
// - pin — fixing which row of a table one path, or one named pick, uses:
// `pinSet`, `namedPick.pins`, `table.drawStep`.
// - family — a table and every table reaching it through a chain of links
// `table.linkParent` makes.
// - fence — a load-time check, run over each category, template or struct as it
// loads or compiles, so rendering a compiled tree cannot fail.
