Third Age section consolidation: remove Tumblr line and deduplicate Notion paragraphs (L692–718)

[MaggieAppleton]

Parent plan

#99

What to build

Clean up the "Third Age" section of src/content/essays/block-party.mdx at lines 692–718:

1. Remove the dangling Tumblr line — cut the stray Tumblr reference that doesn't fit the narrative flow.
2. Consolidate the Notion repetition — the claim "Notion was the most influential" is currently stated three times in different ways. Merge these into a single, well-crafted paragraph that says it once, clearly.

No new writing is required — this is a tightening pass: cut the Tumblr line, identify the three Notion repetitions, pick the best phrasing from each, and combine into one coherent paragraph.

Acceptance criteria

• Dangling Tumblr line at L692–718 is removed
• "Notion was the most influential" claim appears exactly once in the section, as a single consolidated paragraph
• Surrounding prose reads naturally with no orphaned transitions
• No [placeholder] text remains in this section

Sub-issues created

This plan has been sliced into 2 sub-issues, both ready-to-implement:

#	Title	Status
#150	Remove dangling Tumblr paragraph from Third Age section (block-party.mdx L704–706)	ready-to-implement
#151	Consolidate three "Notion was most influential" statements into one paragraph (block-party.mdx L708–717)	ready-to-implement

Both can be picked up immediately and worked in parallel — they touch overlapping lines but are logically independent (one deletes, one consolidates). Neither is flagged needs-human-answer.

Slicing rationale: The two tasks are distinct editing operations — a deletion (Tumblr) and a merge (Notion repetitions) — so they're cleaner to review and verify separately. Either can be merged first without conflicting with the other.
