<!--
Practice template for the document generator (Chapter 14) and the reusable-inputs
chapter (Chapter 19). The parts in {{double braces}} are placeholders the generator
fills in from a data row (for example, a line in clients-sample.csv). Everything else
is fixed wording the tool keeps exactly as written. Small, fake, safe practice content —
no real people or businesses.

Use it two ways:
  - As a LETTER: keep the top block, use the "Letter body" section.
  - As an INVOICE: keep the top block, use the "Invoice" section instead.
Point Claude at this file plus clients-sample.csv and ask it to produce one document per row.
