The center column is gone: Confirm + Clear move onto the tab sub-bar
([tabs] | [Clear][Confirm] | NET value), serving both the trade and
buyback tabs, so the two panels sit side by side with just a bit of
padding between (grid.centerW 208 -> 16). The row description keeps the
smaller font, word-wraps inside the text column (wrap width stops
before the price), and the char-count budget now spans two lines so the
headless path stays bounded; rowH grows 64 -> 72 to fit both lines.
The buttons persist across tab switches (they were content before and
died with it), Confirm stays grayed while the trade is invalid, and the
stub gains setX/setY so the bar layout is testable.
- Shop now opens on the tab sub-bar only (shop video plays); clicking Buy/Sell reveals the trade panel — showcases the clip before the UI takes over.
- Tab bar and Confirm/Clear are now MenuButtons in a console-blue sub-bar that rests above the command deck, anchored to the deck's Shop button (MenuSubBar recipe), replacing the old top-of-screen custom buttons.
- Fix trade panel vertical placement: a Container's (x,y) is a pure translation of local space (verified via dev/cbox-test.html), so the grid position IS the panel top-left; setting it to topY + h/2 treated it as a centered origin and clipped bottom rows. Panel now anchors just under the HUD planet text via SurfaceScene.shopTopY().
- Parent TradeGrid plate/title to the grid container so they render above the shop video (scene-level depth-0 objects drew behind it in this build).
- Add dev probes (dev/cbox-test.html, dev/shop-shot.{html,mjs}) and update phaser-stub/test stubs for setSize/setBlendMode/rectangle; document entry state + sub-bar in docs/ECONOMY.md.
- Introduce CargoHold (pure class) as the ship's trade-goods carrier: fixed bays, one good each, capacity = unlocked bays, save/restore round-trip. Ship.cargo + setCargoHold/cargoRoom wired into stats.
- Add three credit-costed cargo builds (cargo-bay-8/12/16) that expand the hold 4→8→12→16 (MAX wins). BuildWindow affordability now covers both minerals and credits; GameScene.beginBuild debits credit lines and _applyCargoUpgrade expands the hold on completion.
- Add tradePreview/resultingCargo to Economy.js as the shop's pure calculator: sell/buy pricing, net credits, the two caps (can't go negative, end hold fits capacity), and atomic sell-to-free-room-for-buy.
- New ShopView + TradeGrid compose the buy/sell screen over the shop clip: SELL grid of cargo bays (tap to check), BUY grid with quantity steppers, live NET preview, Confirm/Clear, and a session-local Buyback tab (neutral undo at the sale price, locked until a sale). Wired into SurfaceScene's SHOP button.
- data/shopui.json drives the shop layout/animation knobs; economy.json gains cargo.maxSlots (16-slot grid); ship.json base cargoHold drops to 4 unlocked bays.
- Headless tests: dev/cargo.test.mjs (hold rules + trade preview caps), dev/shop-ui.test.mjs (construct, sell, buy, caps, buyback, clear), plus updated builds/ship-behavior suites; phaser-stub gains Geom.Rectangle for the hitArea path.
- Add `front` block to game.json: depth-11 clouds above the ship (parallax > 1) that drift past the player, creating a "flying through" feel vs. the back layer at depth 3
- Implement `shiftHue` in Color.js to derive the front accent from the system's base atmosphere color (hue rotation + lightness lift), making every nebula a stable two-tone gas
- Refactor NebulaAtmosphere into a data-driven layer array with per-layer depth/tint/parallax/drift; extract `spawnCloud` helper; scale swirl speed by configurable drift
- Add 21 new test checks covering accent math (hue delta, identity, white/black preservation, all 8 palette shades) and two-layer structure (depths, tints, parallax ranges, wrapping, destroy, revert path)
- Stub `Phaser.Math.Between`/`FloatBetween` in phaser-stub for Node tests
- Update PROJECT_NOTES.md to document the two-layer model, accent derivation, and new tuning knobs
- 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).
- Add MineralHud component (js/ui/MineralHud.js) showing "MINERALS n / N"
plus a fill bar in the upper-right corner, replacing the old tether
stack. One tween drives both the counting number and the bar so they
never drift; a cyan flash ripples on landings; amber at capacity.
- Wire Mining to emit an onOre(gained, hold) seam per extraction tick and
per fragment landing so the HUD fills live as the rock shrinks, not
only at the batch 'absorbed' event.
- Remove refreshTetherHud / fmtRange from GameScene; instantiate MineralHud
in create(), feed it via refreshMineralHud() from ore seams and mining
events, destroy on shutdown.
- Add data/mineralhud.json config (corner pad, bar geometry, count-up and
flash tuning) and register it in the manifest.
- Tests: new dev/mineral-hud.test.mjs covering layout, count-up/bar sync,
superseded-tween guard, capacity/clamping, teardown; extend
dev/mining.test.mjs to assert onOre ticks; drop tether-HUD checks from
dev/system-hud.test.mjs; add setOrigin/setScrollFactor no-ops to the
Phaser stub.
- Extract minerals from the latched asteroid at ratePerSec × miningSpeed; each mineral shrinks the rock by 1 px so the beam stays latched to its rim.
- Break rocks that lose ~1/3 of their original size: large ones halve in place (beam keeps mining one half), small ones shatter into pieces that fly home and load the hold.
- Add ship.minerals hold with addMinerals/setMinerals capped at stats.mineralStorage; a full hold ends the run instead of grinding the rock away.
- Persist the hold in save/restore (captureState writes ship.minerals, applyRestore restores it) and keep legacy saves working when the field is absent.
- Play new mining_split sfx on each break and surface split/absorbed/storageFull events as console toasts.
- Expose AsteroidCluster rock surgery (setSize/addRock/removeMember) for runtime splits, and add headless Phaser stub + loader plus a mining test suite covering extraction, halving, shattering, full-hold stop, and the hold API.
