Bản mẫu:Source unit
This is the source of the wiki page Template:Source unit.
Usage:
— marks where source unit 3 starts in an Original-transcript page whose source is not a paginated PDF (PDF pages use Template:Pdf page): a workbook TAB for a spreadsheet, a filing SECTION (cover / statement / Item) for an SEC document (design/twolayer_all_formats.md §4). Renders the same right-aligned mono chip as
, labeled with the unit's printed name (fallback "unit N"), linking
the source document; sets an id="pN" anchor so talk-page comments can link Page#p3.
quiet: with |quiet=1 the visible chip is SUPPRESSED (SEC — the ## unit heading right below already names the unit, so the bracketed [Item 1.…] chip is redundant apparatus; user 2026-08-08). The id="pN" anchor is ALWAYS emitted — it is load-bearing (legacy c. {{{c}}}; p. N markers and Page#pN links target it). Workbook tabs omit quiet and keep their chip.
The deriver maps it back to the Original .md's marker (tools/doc_archive/output/original_derive.py — reads only the page number, so quiet is round-trip-invisible). Styling shares .ed-pdfpage in MediaWiki:Common.css — no separate class.
