PowerPoint templates

Reference for translating a deck authored on Microsoft's stock Office Theme template onto the Polyrhythm .potx templates - manually (PowerPoint > Layout) or programmatically. The Polyrhythm layouts were built to match Office's OOXML slide-layout type and placeholder type/idx/sz, so most content relayouts 1:1.

Source of truth: generated from the committed templates by _repo/scripts/pptx/layouts.mjs. If you change a layout's placeholders or reorder nums, re-render and update the IDs below (they are the master's sldLayoutIds and the slideLayoutN.xml part names, assigned in num order).

How a translator should work

A slide does not reference the sldLayoutId directly - it references a slideLayout part through a relationship in its .rels (slideN.xml.rels -> Target="../slideLayouts/slideLayoutNN.xml"). The sldLayoutId lives in the master's sldLayoutIdLst and is given here only so a tool can cross-check. The three keys to a translation:

1. Match the source layout by its OOXML type and Office layout name. The name is required to disambiguate: type="obj" and type="twoObj" are each shared by several layouts, so type alone is not enough (e.g. Two Content vs. Comparison are both twoObj).
2. Retarget the slide's layout relationship to the Polyrhythm slideLayoutNN.xml part below. Pick the dark or light .potx as the theme - the IDs and part names are identical in both, so theme is purely a file choice.
3. Remap placeholders by (type, idx) per the row. Identity in most rows; the exceptions are flagged (Section Header needs idx 1 -> idx 2). sz (full/half/quarter) is a cosmetic hint and never affects matching.

Polyrhythm adds two extra placeholders to most layouts - the editable classification/distribution zones at body idx 13 and body idx 14. They have no Office source and are simply left as empty prompts (hidden until filled).

The matrix - 11 standard Office layouts

Placeholder columns list type/idx (a bare number = a content placeholder with no type attribute, i.e. Office's "Content Placeholder", schema-default obj).

Office layout	Office type	Office placeholders	-> Polyrhythm target	sldLayoutId	Part	Polyrhythm placeholders	Placeholder remap	Notes
Title Slide	title	ctrTitle - subTitle/1	PR-01 Title Cover	2147483651	slideLayout2.xml	ctrTitle - subTitle/1 - body/2	identity	body/2 = deck-info (rev/date/customer); no Office source. Alt: PR-02 Formal Cover (2147483652, slideLayout3.xml).
Title and Content	obj	title - 1	PR-00 Base Content	2147483650	slideLayout1.xml	title - 1	identity	Canonical obj target - match by name, since 10+ PR layouts are type="obj".
Section Header	secHead	title - body/1	PR-05 Section Divider	2147483655	slideLayout6.xml	body/1 - title - body/2	title->title; body/1 -> body/2	Remap required. PR body/1 is the small section-code kicker (above the title); the Office text belongs in PR body/2 (summary, below the title). Naive idx-matching mis-places it.
Two Content	twoObj	title - 1 - 2	PR-07 Two Content	2147483657	slideLayout8.xml	title - 1 - 2	identity	Shares twoObj with Comparison - disambiguate by name / absence of body headings.
Comparison	twoObj	title - body/1 - 2 - body/3 - 4	PR-19 Comparison	2147483668	slideLayout19.xml	title - body/1 - 2 - body/3 - 4	identity	Exact 1-4 parity. body/1 & body/3 are the column headings; 2 & 4 the bodies.
Title Only	titleOnly	title	PR-06 Thesis	2147483656	slideLayout7.xml	title - body/1	title->title	Only titleOnly match, but Thesis restyles the title as one oversized statement and adds an attribution (body/1). No neutral title-only canvas exists - see Gaps.
Blank	blank	(none)	PR-10 Full Content	2147483660	slideLayout11.xml	1	n/a	No blank layout exists. Free-form shapes carry over regardless of target; Full Content gives one open area with no title. See Gaps.
Content with Caption	objTx	title - 1 - body/2	PR-18 Content with Caption	2147483667	slideLayout18.xml	title - 1 (half) - body/2 (quarter)	identity	Exact parity. 1 = large content (right), body/2 = caption (left).
Picture with Caption	picTx	title - pic/1 - body/2	PR-20 Picture with Caption	2147483669	slideLayout20.xml	title - pic/1 - body/2 (quarter)	identity	Exact parity. Alt: PR-23 Team / SME Profile (2147483670, slideLayout21.xml) adds body/2 role line + 3 credentials - use for people.
Title and Vertical Text	vertTx	title - body/1	PR-00 Base Content	2147483650	slideLayout1.xml	title - 1	title->title; body/1->1	No vertical-text layout; verticality is lost. Rare. See Gaps.
Vertical Title and Text	vertTitleAndTx	title - body/1	PR-00 Base Content	2147483650	slideLayout1.xml	title - 1	title->title; body/1->1	No vertical layout; verticality is lost. Rare. See Gaps.

Gaps - Office layouts with no clean Polyrhythm target

These map with loss; address by authoring a new layout in layouts.mjs if the content type is common in your source decks.

• Title Only -> mapped to Thesis (titleOnly), but Thesis is an opinionated single-statement layout. There is no neutral "title + open canvas". Fix: add a plain titleOnly layout (shared contentHead title, empty body).
• Blank -> no blank layout. Free shapes survive any retarget; Full Content gives an open, title-less area. Fix: add a type="blank" layout (classification zones only) for true blank parity.
• Title and Vertical Text / Vertical Title and Text -> no vertical-text layouts; mapped to Base Content with vertical orientation lost. Rare in practice; add vertTx / vertTitleAndTx layouts only if needed.

All other standard Office layouts have exact or near-exact (idx-faithful) Polyrhythm targets.
