- New `js/utils/Decode.js` with a pure `ScrambleDecode` class plus
`DECODE_CHARS`, `DECODE_DURATION`, and a per-line `decodeDur()` helper,
so one effect serves both scenes.
- MenuScene now delegates its seed scramble to the shared utility instead
of inlining the reveal math and alphabet.
- GameScene's system dossier types itself in on arrival: each line starts
empty and decodes left-to-right, staggered top-to-bottom, with the
timeline anchored on the first update frame; state self-clears once all
lines settle so `update()` pays nothing afterward.
- Add Node dev tests for the shared effect contract (`dev/decode.test.mjs`)
and for the real GameScene dossier decode against actual galaxy/report
data with a stubbed scene (`dev/system-hud.test.mjs`).
- Document both new test commands in the README and update the planets
PSD asset.
Adds the player's home planet to the starting system, rendered from the new
planets.png spritesheet. The planet is a solid disc: the ship may come within
shipClearance of its rim but can never cross it, and clicks on the planet
clamp to the keep-out rim so the ship always has a reachable destination.
- js/entities/Planet.js: solid-disc entity with a circle keep-out constraint
(constrainShip/resolve, pure and scene-free) plus edgePoint/aimPoint helpers
- data/planets.json (+ manifest entry): texture, frame size, scale, homePlanet,
shipClearance, spawnDistanceFromEdge
- Ship.js: exposes a radius (half the hull width) for the keep-out math
- GameScene.js: loads the spritesheet, spawns the home world at the origin,
starts the ship ~150 px off its rim in a seed-derived direction, and applies
the constraint each frame after the ship moves
- dev/planet.test.mjs: Node tests of the constraint against real config;
dev/test-game.html gains a <base href> so asset paths resolve from /dev
