## ruflo-console 0.43.0: optional Orbital look and Theme Studio

Classic BBS stays the default. Orbital is opt-in; nothing changes until you pick it.

### Changelog
- **feat:** an optional **Orbital** look: black telemetry panels, square borders, a rotating globe, a scan sweep and a shaded RUFLO header that stays visible after boot (Main Menu, Theme Studio, Swarm), animated real boot checks, a perspective swarm preview.
- **feat:** **Theme Studio** (Main Menu → Tools, Settings, or `/ruflo themes`): pick Classic BBS, Terminal plain or Orbital; six bundled color presets; up to twelve named custom themes saved through host storage; a color picker with a 3:1 minimum contrast; motion layers and speed; `fps` 0 freezes the frame.
- **feat:** a bundled `generate-console-theme` skill (`allowed-tools: Read`) returns data-only palette/motion JSON for Claude or Codex; import goes through a strict, 4096-character-bounded schema.
- **fix:** Theme Studio has a boot-log line and a help guide and is reached by name; the wide Orbital header says RUFLO, not RUVNET.
- **chore:** the globe reads a one-degree land mask built once (about a third less time per frame); `scripts/bench-theme.mjs`; no Python in the repo (the SVG demo exporter is Node).

### Validation
- Console tests: 0 failing (main and this release both skip 29 files that need `claude-code/testing`); 3193 pass (+77). Console smoke 20/20; manifest, mcp-prefix, skill-frontmatter, hook audits and `claude plugin validate` pass; CI 114 checks green.
- Checked in the real Claude Code 2.1.289 (isolated config, directory marketplace, tmux, frames viewed): `/ruflo`, Orbital and Classic, Tools → Theme Studio, `/ruflo themes`, colour edit, contrast guard, save and reload across a full restart, "Use configured look", malformed/hostile JSON rejected with the theme unchanged, animation running (12/12 distinct frames) and stopped at `fps` 0, resizes 300→150 columns, clean model-facing `console_state` (no escapes, no theme JSON).
- 45 adversarial specs on import, stores and model-facing text found no defect. Classic BBS per-tick cost is unchanged from before.

### Not verified
Windows and macOS terminals, other emulators (tmux 256-colour only), the desktop and VS Code surfaces, a real AI-generated theme round trip (Generate with Claude/Codex was not run), and some stray `│` cells right of the pane after a shrink-resize in tmux (looks like host diff-render residue). The side-by-side editor layout needs a pane of 100+ columns (the host's default share is narrower; `RUFLO_CONSOLE_COLUMNS` widens it).

### Install
Marketplace plugin, not npm: `claude plugin marketplace update ruflo` then `claude plugin update ruflo-console@ruflo`, and restart Claude Code.
