// ─── +chart-create --print-example ─────────────────────────────────────
//
// chart-create's --properties schema is ~1,750 pretty-printed lines; eval
// traces show agents paging through the full --print-schema dump for every
// chart (25 round trips in one 35-task batch) and still missing deep
// required fields. A ready-to-edit minimal template per chart type answers
// the actual question ("what does a valid payload look like") in one local
// call. Wired through PostMount, same pattern as +csv-put's flag-group
// tweaks — no framework change.
//
// Templates mirror the canonical examples in the lark-sheets-chart
// reference (sheet-skill-spec canonical-spec/references/lark_sheet_chart):
// inline headerMode with refs covering the header row, 1-based indices,
// quoted sheet prefix in refs.
