Add a hexagonal Community Home

[baxen]

Why

Buzz needs a stable, useful place to land when no community is selected, rather than treating onboarding as a global mode that can wedge the app.

What

• Add a responsive honeycomb Community Home for opening, joining, creating, and removing saved communities
• Make the active community selection nullable and expose Home from the persistent community rail
• Return cleanly between Home and the join flow, including the zero-community state
• Cover rendering, selection, join/back navigation, and the visual layout with focused Desktop E2E tests

Risk Assessment

Medium — this changes Desktop startup and community-selection behavior, but is isolated to the community shell and covered by static checks, unit tests, build, and focused E2E tests.

🐝 Design refinement pass — Community Home

Independent visual/design review by Honey, using the design guidance (heuristics only, no commands) from Impeccable. Underlying behavior (nullable selection, join/create/remove, navigation) is unchanged — this is a visual-only pass.

Before

The hexes didn't interlock (large gaps → scattered, not a honeycomb), the dark Join/Create actions dominated over the actual communities, and the community tiles were washed-out and flat.

After

A true interlocking honeycomb (pointy-top tessellation, ResizeObserver-driven, balanced rows). Communities read as elevated hero tiles; Join/Create become lighter, additive cells. Icon tiles squared, contrast/borders strengthened, clip-path-safe drop shadow for real elevation.

Hover / focus

Tile lifts with a primary outline and an "Enter →" hint; ease-out motion with a prefers-reduced-motion fallback.

Responsive

The comb reflows and stays interlocked at narrow widths (hex size + columns adapt).

Empty state

With no saved communities, the two additive cells center cleanly over the helper copy.

Validation: biome lint + tsc clean, check:px-text guard clean, production build green, and the 4 focused community-home E2E tests pass.

Community Home, re-imagined: grow your own hex lattice

Reworked after @baxen closed this to rethink the model. Community Home is no
longer a grid of community tiles — it's a single connected honeycomb you
build out, with agents, communities, and relays all peers on one board.

The model

• Mostly-blank page with the gradient background showing through.
• Center hex = you — your profile, with a default for someone who has no
  relay yet. Works fully offline (useIdentityQuery).
• Hover to grow: idle shows only your filled cells; moving into the area
  reveals the connected frontier — faint ghost cells plus three live create
  tiles (New agent · New community · Connect community).
• One regular, fully-connected lattice (axial hex coords → absolute pixel
  positions), not floating hexes. Only hovered or filled cells are ever visible.

Fresh — just you

Fresh — hover reveals the create frontier

Populated — your communities on the lattice

Populated — hover reveals frontier + create tiles

---

Under the hood

• Communities (useCommunities) and local managed agents
  (useManagedAgentsQuery, offline) spiral outward from center as filled hexes.
• "New agent" wired via requestOpenCreateAgent; RequestedAgentCreateDialogs
  is mounted here so it works before any relay is connected.
• Hidden create tiles are pointer-events-none so a blank-area click can't
  fire an action; keyboard focus re-enables them. Required lattice radius is
  never capped, so no cell is ever silently dropped.

Validation: biome + tsc clean · check:px-text clean · production build
green · full desktop E2E smoke/integration 633 passed, 0 failed. The
buzz-push-gateway pre-push Rust failure is unrelated (this commit is desktop
TS/TSX only); CI re-runs the authoritative gate.
