docs: Layer 2 — CDN-verified FoF comments (per-V_x keypair)

Browse source 
Replace single per-post priv_post with per-V_x (pub_x, priv_x). Post
header publishes pub_post_set; comments declare pub_x_index; CDN
propagation nodes verify group_sig + identity_sig against named pubkey
before forwarding. Kills bandwidth-amplification DoS from admitted-but-
malicious FoF members.

Dual-derivation wrap slot (read → CEK, sign → priv_x) with shared
structure Layer 3 inherits. Comments encrypted under CEK_comments so
Mode 2 comments are genuinely FoF-read-gated, not just FoF-sign-filtered.

Author-signed revocation diff appended to post; CDN honors per-chain
revocation. Tradeoff: pub_x_index is a per-post voucher-chain pseudonym,
re-randomized across posts. Accepted.

Layer 3 banner added noting wrap-slot structure is now superseded by
Layer 2's canonical form; full reconciliation deferred.

# Layer 3 — Mode 1: `FOF_CLOSED` Posts
> **⚠️ Partially superseded by Layer 2 rewrite (2026-04-24).** Layer 2 now defines the canonical wrap-slot structure (dual read/sign derivation), `pub_post_set`, per-`V_x` signing keypair, and CDN-level verification. Layer 3 inherits all of that unchanged — the Mode 1 vs Mode 2 distinction reduces to "body encrypted under CEK (Mode 1) vs body plaintext (Mode 2)." The sections below still reflect the earlier single-keypair design and will be reconciled when Scott + Opus review Layer 3.
**Scope**: New `PostVisibility::FoFClosed` variant. Both post body AND comments are gated to the FoF graph. Body is encrypted; readership emerges from keyring intersection with `wrap_slots`.
Builds on Layer 2's `pub_post` / `priv_post` / `wrap_slot` primitives — same structures, just that the CEK encrypting the body is *also* in the wrap slots (alongside `priv_post`).
