Remove AI-slop patterns from blog posts

[krMaynard]

What changed

• edited all 48 English source posts using the no-ai-slop skill rubric
• removed repeated em-dash cadence from prose, headings, titles, and descriptions
• replaced canned setups and filler such as “Here’s the thing,” “It’s worth noting,” and “That’s it”
• untangled the affected sentences without changing claims, statistics, links, or article structure

Why

The posts leaned heavily on a few recognizable AI-writing habits, especially decorative em dashes and formulaic framing. This pass keeps the data-heavy, direct voice while removing those repeated patterns. Translations are intentionally out of scope because the skill is an English editing rubric.

Validation

• checked all edits against no-ai-slop/eval.md
• scanned for the skill’s banned words and named patterns
• parsed all 48 HTML files and verified front-matter delimiters
• git diff --check
• npm test (86/86 passed)
