- Nebula gas layer: soft coloured cloud sprites at depth 3, tinted with a
per-system palette color assigned deterministically at galaxy generation
(SystemGenerator stamps content.atmosphere.color). Only nebula-type
systems render it; all other types are untouched.
- Ripple effect: a full-screen WebGL composite on the world camera that
displaces the starfield and world objects while the HUD stays crisp via
a new UI/world camera split (UiCameras.js). Data-driven per archetype in
data/systems.json (nebula = ripple, all others = none). Canvas fallback
degrades to no effect.
- Demo mode: ?fx=<type> URL param retargets the run to the richest system
of that archetype, fully charted with all gates active, for judging the
effect in isolation.
- New ice and lava planet art (slots 9–14 in planets.png) replacing the
placeholder terran/rocky/gas reuse.
- Node test suites for the nebula palette/determinism/cloud texture and
the ripple math/data contract/shader/facade (50+ checks, bare Node).
The overlay was drawing the sweep image and glitch burst bars at negative-x offsets (e.g. `-w/2`) as if in a centered coordinate system, but Phaser graphics/images live in scene space starting at 0. This shifted the sweep left by half the viewport and clipped the glitch bars off-screen. Anchor them to `0` / `w/2` so they align with the visible area.
- Boot the game from a static server with no build step (Phaser 4 vendored in lib/)
- Main menu (New Game button) and GameScene where clicking makes the ship fly there
- All tunables live in data/*.json (game/menu/ship), loaded via manifest + Config singleton
- Ship behavior driven by arcade physics (thrust, drag, maxSpeed, arrival) with a Node test harness (dev/ship-behavior.test.mjs) and a dev smoke page that boots straight into GameScene
- Project conventions documented in docs/PROJECT_NOTES.md; README rewritten to describe layout, run instructions, and dev tools
