- Play thunder claps on habitable storm strikes, solar-flare SFX on red
dwarf flare onset, and solar-buzz on binary light-trade midpoint
crossings, all via the shared Sfx voice (new playSfxOneOfOn helper)
- Add per-context music volume overrides (music.volumes) so each context
can deviate from the global mix; menu ships at full volume
- Expand surface music frames to cover rocky and ice worlds (frames 6-11)
- Teardown per-system effect layers on scene restart (jump) so a previous
system's storm doesn't keep striking and playing thunder in the new one
- Update planets.png sheet, add gasgiant-03/rocky-01/rocky-02 tracks, and
register the new SFX assets in GameScene preload
- New StormLayer renders purple cloud clusters with a seeded charge → strike → afterglow envelope in the upper sky, using sprite compositing (back/flash/front trios) rather than shaders
- Add `stormEnvelope` + `sstep01` to SystemEffectsMath.js; refactor NebulaAtmosphere's cloud shape into a shared `cloudAlpha` used by both `drawCloud` and the storm's flash texture
- Extend EmberField with optional per-spark twinkle (rate/depth) so habitable fireflies pulse while redDwarf embers stay steady
- Wire StormLayer create/update/destroy into GameScene alongside the other content effects
- Populate `types.habitable.effect` in systems.json with grade, void, particles, and storm blocks; update landing.json to use ice land/takeoff videos for slots 02 and 03
- Add 7 new test checks covering the storm envelope math, habitable data contract, bundle sanity, and facade apply(); bump live types from three to four
- Add VoidBase content layer (neutral dark+grit surface at depth -1) so the
grade shader's two-light shadow lift can paint amber/azure onto the void
(the clear color bypasses filters)
- Extend grade shader with uLift2* and uBreath uniforms: side A glows color 1,
side B glows color 2 across the seeded axis, with a slow sinusoidal trade
- Wire breath period/depth from config into per-frame update()
- Rework WandererStar to anchor to the camera view each frame (wrap-in +
parallax trail) so it stays visible in the sky regardless of ship travel;
increase default core/halo sizes for a more present companion star
- Update systems.json binary effect with lift, breath, void config and larger
wanderer sizes
- Add test coverage for the new two-light lift, breath animation, and shader
uniform declarations (59 checks total)
- Replace the single `kind: ripple|none` effect with optional per-type blocks (ripple, grade, flare, haze, particles, wanderer) so each archetype wears exactly what it lists
- Add redDwarf visual identity: super-subtle star-anchored ripple that surges on a seeded flare, warm color grade with shadow lift + grain, a gritty red haze behind the stars, and drifting ember dust
- Add binary visual identity: two-color directional split grade plus a wandering companion star (no ripple)
- Generalize the ripple shader/filter to up to two orbiting centers and drive both the ripple amplitude and the grade flash from one shared flare signal
- Stamp per-system fx variation (phase/angle/drift) in SystemGenerator so each system's flare rhythm, split axis, and wanderer path are stable but distinct
- Add EmberField, RedHaze, WandererStar content layers wired into GameScene create/update/shutdown
- Update the data contract, 57-check test suite, project notes, and landing/systems JSON; add ice landing/takeoff video assets
- 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).
