redoal showcase page + a memory/preservation deep-dive

A visitor-facing /redoal page (the drawing is the address; voices live
where their people are; memory protects what's rare) whose 'how the
memory works' alternative routes to /redoal/memory — attention
replicates, scarcity retains, the speaker anchors, letting go is safe.
Lint-clean (question_lint: 11 questions valid). Not linked from any
page yet — wire an entry point (e.g. an index alternative) when ready.

+name: A place is a gesture
+description: >
+  redoal is a voice network with no map and no server holding the
+  words. You draw a shape; that drawing *is* an address. Anyone who
+  draws something close enough arrives at the same place, hears the
+  short recordings left there, and can leave their own. The people at a
+  place are its infrastructure — their phones hold its memory between
+  them.

+    description: >
+      No central store, no account, no directory. The network is the
+      phones that show up, and it stays alive by a few ideas working
+      together.

+          A gesture becomes a 20-byte key that reconstructs back into
+          the line you drew. Similar drawings land at the same place —
+          so a place is found by feel, not by name, and nothing needs a
+          lookup table to know where anything lives.

+          Recordings are held on the devices of the people who visit a
+          place, handed peer to peer. Attention is the storage: the
+          more a voice is heard, the more phones carry it, and the
+          harder it is to lose.

+          Your phone can't hold everything, so it keeps the voices
+          *few* others do — releasing the ones already safe on many
+          devices, holding the ones in danger of vanishing. The network
+          preserves itself without anyone deciding what survives. Tap

+          When a relay helps, it points visitors *toward* each other —
+          it never becomes the place the words live. The fewer servers
+          it takes to keep a voice reachable, the more the network is
+          doing what it was built to do.

+name: How redoal remembers
+description: >
+  A place's voices should stay reachable as long as people care about
+  them, and no longer — and no phone should fill up preserving voices
+  nobody returns to. redoal gets there with three ideas that need no
+  coordinator: attention spreads a voice, scarcity keeps it, and the
+  person who spoke it is the anchor of last resort.
+alternatives:
+  - name: The three forces
+    description: >
+      No server decides what survives. The incentives do — and they
+      pull in exactly the right directions.

+      - name: Attention replicates
+        icon: lucide:ear
+        description: >
+          Every time someone listens to a recording, their phone keeps
+          a copy and quietly announces itself as another place you can
+          get it from. A voice heard by a hundred people is, by that
+          fact alone, held by a hundred phones. Listening is hosting.
+      - name: Scarcity is kept
+        icon: lucide:gem
+        description: >
+          When a phone runs low on room, it doesn't drop the oldest
+          voice — it drops the *safest* one. The network already knows
+          how many phones hold each recording, so each device
+          preferentially keeps the ones held by almost no one, and lets
+          go of the ones held by many. Everyone reaching for the rare
+          voice means the rare voice is exactly what gets protected.
+      - name: The speaker anchors
+        icon: lucide:anchor
+        description: >
+          Whoever left a recording never forgets their own — a place's
+          origin is always reachable through the person who made it.
+          Below everything else, the author is the backstop, so no
+          voice can fall all the way out of the world while its speaker
+          still carries a phone.

+        icon: lucide:recycle
+        description: >
+          A phone releasing a voice isn't deleting it — the drawing
+          still leads there, and the network fetches it back on demand
+          the next time someone arrives wanting it. Reclaiming space
+          and preserving memory are separate, which is what lets a
+          small phone be a full member without fear.
