Add pptx slide-deck build target for screen-share recordings

Same markdown now also builds a PowerPoint deck (make slides /
make template.pptx) alongside the existing PDF, for recording
walkthrough videos. Styling comes from reference.pptx since pandoc's
pptx writer ignores style.css; its theme was hand-tuned to match the
PDF's dark palette and fonts.

Restructure the closing block into a two-column div so the author
photo survives in slide exports (pandoc drops images sharing a plain
div with paragraph text), with a CSS override so the PDF keeps its
original centered layout.

+## Building slides
+
+For recording a screen-share walkthrough of the guide, the same markdown builds
+a PowerPoint deck instead of a PDF:
+
+```sh
+make template.pptx              # slide deck for the base version
+make partners/<slug>.pptx        # a specific partnership's deck
+make slides                      # template.pptx + every partners/*.pptx
+```
+
+Pandoc turns each `##` heading into its own slide, matching the "one step per
+page" layout of the PDF. If you want scripted talking points per slide, add a
+`::: notes` ... `:::` fenced div under a heading — pandoc exports those as
+speaker notes rather than slide body text.
+
+Pandoc's pptx writer doesn't read `style.css` (pptx isn't HTML-based), so the
+slide theme instead comes from `reference.pptx` — a PowerPoint file whose
+slide master carries the colors and fonts, built once by hand-editing its
+theme XML to mirror `style.css`'s dark background, heading blue, body text,
+and accent colors, plus Roboto/Open Sans fonts. Edit it in PowerPoint/Keynote/
+Google Slides (or its `ppt/theme/theme1.xml` and
+`ppt/slideMasters/slideMaster1.xml` directly) if the slide theme ever needs to
+diverge from or resync with the PDF's.
