BitBlocks umbrella site — the parent identity for the stack

A monochrome, architectural landing tying BitLogin/BitGate/BitFeed/BitUnlock/
Tessera into one message. Parent brand distinct from every product
(Alphabet-to-Google): the five product colours are the only chroma; monumental
condensed Ubuntu Sans display, mono annotation layer, theme-aware. Sections:
tenant->owner thesis, the five blocks, how they compose (Tessera as the worked
example), foundation principles, builders CTA. Static, no build, CSP-locked.

+# bitblocks.network
+
+The umbrella site for the BitBlocks stack — composable Nostr + Bitcoin building
+blocks for apps that can't lock anyone in.
+
+Static site, no build step. Deployed to the apex `bitblocks.network`.
+
+## The blocks
+
+| Block | Question | Site |
+| --- | --- | --- |
+| BitLogin | who are you | login.bitblocks.network |
+| BitGate | what may you do | gate.bitblocks.network |
+| BitFeed | what do you see | feed.bitblocks.network |
+| BitUnlock | how you're paid | bitunlock.network |
+| Tessera | what you can do | tessera.bitblocks.network |
+
+## Design
+
+Deliberately distinct from any single product: a monochrome, architectural
+parent identity where the five product colours are the only chroma — the
+Alphabet-to-Google relationship rendered in design. Monumental condensed
+Ubuntu Sans display, Ubuntu Sans Mono for annotations, theme-aware.
+
+## Local
+
+```sh
+python3 -m http.server 8080   # then open localhost:8080
+```
