Späti’s fork (second-brain-public)

Simon Späti’s public second brain (ssp.sh/brain) runs a heavily customized
Quartz v3 fork: sspaeti/second-brain-public
(MIT, hugo branch, actively maintained). His customizations over upstream:

• #publish tag pipeline — tagging a note #publish in his private Obsidian
  vault automatically copies it into the public repo (his private→public gate;
  ours is the publish: true frontmatter key).
• H1 → frontmatter — first # heading is converted into title frontmatter.
• Smart description extraction — first paragraph cleaned of wikilinks,
  markdown formatting, list markers.
• Raw Markdown per note — every note is also served as plain Markdown at
  /brain/<slug>/index.md, so LLMs/scrapers read the Obsidian source without
  site chrome. See Digital gardens.
• Fork additions — case-insensitive link matching, block-reference
  (^hash) handling, slash-in-title normalization, large-vault perf tuning.
• FlexSearch modal — full-screen search across blog + brain together.

His stack: Obsidian (private vault) → Quartz v3/Hugo → ssp.sh/brain.
Ours: Obsidian (this vault) → Quartz v5 → brain.krzysztofkaminski.dev.
