2026-10-17 - Concept pages rehomed to General Knowledge

Principle: General Knowledge is the canonical home for explanation and reference; Business Bootstrap is the curated how-to path that links there (same pattern as code signing in the release pipeline and Cloudflare Access for static sites).

Moved to general-knowledge (old URLs alias there): Cloudflare Email Routing limits, Personal Gmail send-as gotchas, DMARC policy path, Human vs product messaging, ITIL-shaped email services, Resend subdomain DNS roles, Email provider comparison, Org infra repo pattern, Pulumi Cloud org model, Pulumi secrets vs stack state, OSS funding landscape, Donation ask ideas.

Kept here (bootstrap-specific): tutorials, how-tos, Email decision matrix (our defaults), Defaults by org stage, Software stack, vendor-choice pages (Cal.com, Penpot, Bitwarden/Vaultwarden, Mattermost), GCP transfer, Pulumi state backup, Pulumi + Cloudflare email checklist.

Email, Org infra, and Funding area pages list the GK pages under a "Background in General Knowledge" section; nav.adoc links straight to them.

All inbound xrefs rewritten to general-knowledge::.
