paliad/scripts/gen-skeleton-submission-template/main.go

// Universal-skeleton submission template generator (t-paliad-259).
//
// One-shot authoring tool that emits a minimal but Word-compatible
// .docx file exercising every placeholder SubmissionVarsService
// resolves — without baking in any submission_code-specific prose.
//
// Drop the output into m/mWorkRepo at
//
//	6 - material/Templates/Word/Paliad/HLC/_skeleton.docx
//
// so paliad's submission generator picks it up via the fallback chain
// slotted between the per-submission_code template and the bare
// universal HL Patents Style .dotm. Any submission_code that has no
// per-firm template still gets a draft populated with variables
// instead of the macro-only letterhead.
//
// Why a separate file from de.inf.lg.erwidg.docx: that one is a
// Klageerwiderung skeleton (DE LG, "I. Anträge / II. Sachverhalt /
// III. Rechtsausführungen"). For a UPC SoC, an EPO opposition, a DPMA
// appeal, that body structure is wrong. The universal skeleton drops
// the structure and leaves a single neutral body block the lawyer
// replaces — every variable still resolves regardless of code.
//
// Run:
//
//	go run ./scripts/gen-skeleton-submission-template -out /tmp/_skeleton.docx
//
// Output is byte-reproducible (zip mtimes pinned to a fixed UTC
// timestamp).

// reference them where it actually wants them.
//
// Every placeholder occupies its own <w:r> run so the renderer's pass-1
