Source and add historical images (Xanadu, NLS, HyperCard, OLE, OpenDoc)

[MaggieAppleton]

Parent plan

#92

What to build

Replace five historical-image placeholders in src/content/essays/block-party.mdx with real images sourced from Wikimedia Commons, public-domain archives, or the essay's existing references:

Line	Placeholder	Source
648	[image of xanadu's parts]	Wikimedia Xanadu screenshots, or the transclusion diagram from Ted Nelson's papers
654	[image of NLS]	Mother of All Demos frame grabs (public domain)
666	[image of hypercard]	HyperCard stack screenshot from Wikimedia
672	[OLE diagram]	Microsoft docs diagrams or a simple custom version
680	[OpenDoc diagram]	The OpenDoc paper (already in references) has reusable diagrams

Images should be placed in the appropriate public/ assets directory (check where other essay images live), and referenced with <Image> or <img> components consistent with the rest of the essay.

Acceptance criteria

• All five placeholder lines replaced with actual image components
• Each image has an appropriate alt text describing its content
• Image files committed to the repo (or hosted externally with stable URLs)
• Attribution/license noted in a caption or comment where required (Wikimedia CC images need attribution)
• File renders without MDX errors and images display correctly in dev

Blocked by

None — can start immediately (these are all public-domain / openly licensed sources, independent of Figma inventory)

Sub-issues created

Sliced into 4 independently-grabbable sub-issues, one per image or logical group:

Sub-issue	Scope	Label
#146	Add Xanadu diagram image (L648) — source from Wikimedia or Ted Nelson's papers	ready-to-implement
#147	Add NLS / Mother of All Demos image (L654) — public domain frame grab	ready-to-implement
#148	Add HyperCard screenshot (L666) — Wikimedia or Computer History Museum	ready-to-implement
#149	Add OLE diagram + OpenDoc diagram (L672 + L680) — two images in one PR, same section	ready-to-implement

All four are ready-to-implement — no blocking questions. Each implementer should:

1. Commit image files to src/images/posts/block-party/
2. Replace the bracket placeholder with a <BasicImage> component (see growing-a-human.mdx for the import pattern)
3. Include alt text and attribution/license where required (Wikimedia CC images need a caption credit)
