Eligible cosmetics expose a preview action. Store and inventory modals open and close the preview. The modal displays metadata, palettes, controls, and localized labels.
Preview maps and animation
src/client/render/preview/PreviewMapGenerator.ts, src/client/render/preview/PreviewAnimationTicker.ts, tests/CosmeticPreviewRenderer.test.ts
Adds terrain presets and deterministic animations for skins, buildings, trails, nukes, salvo mode, and MIRV effects.
WebGL preview passes
src/client/render/preview/passes/PreviewSkinPass.ts, src/client/render/preview/passes/PreviewExplosionPass.ts
Adds skin, pattern, fallback-color, and procedural explosion rendering passes with resource cleanup.
Preview renderer and canvas controls
src/client/render/preview/CosmeticPreviewRenderer.ts, src/client/components/cosmetics/CosmeticRenderCanvas.ts
Combines preview maps, animation snapshots, textures, rendering passes, camera controls, trails, units, structures, explosions, and input controls.
Rendering defaults and fallbacks
src/client/WebGLFrameBuilder.ts, src/client/render/types/Renderer.ts, src/client/render/gl/passes/fx-pass/*
Adds defaults for explosion parameters, shared explosion duration calculation, shockwave buffer updates, and guarded atlas loading.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to 0e223

The preview modal is mergeable with explicit owner follow-up because custom colors currently do not appear in the spiral ribbon preview, creating a bounded cosmetic-preview correctness issue without broader production impact.

A cosmetic leaves its card,
The preview map starts to glow.

Derive maxDist from the target list.

maxDist is 154.2, but the distance from pApex to { x: 256, y: 320 } is about 154.26. The ratio d / maxDist can therefore exceed 1 and push hitTime slightly past MIRV_FLIGHT_DURATION_SEC. The detonation loop still fires, so behavior is correct today. Compute the value instead of hardcoding it, so a future edit of MIRV_WARHEAD_TARGETS or pApex stays consistent.

Reduce per-frame trail allocation.

Each sample() call rebuilds the full trail and pushes one new object for every rasterized pixel. The MIRV path does this for 8 targets with 61 interpolation steps each, so one frame creates thousands of short-lived objects. At 60 fps this creates steady GC pressure while the modal is open.

Two options:

  • Keep a reusable Float32Array (or parallel typed arrays for x, y, timestamp) and write into it instead of pushing objects.
  • Cache the static parts of the trail. The apex-to-target paths do not change inside a cycle; only the visible length changes.

Consider a smaller quad per explosion.

Each explosion draws the full map quad, so the fragment shader runs over the whole viewport and discards most fragments. A MIRV cycle produces 8 explosions, which means 8 full passes per frame. Pass a center and radius as extra uniforms to scale the quad to the explosion bounds, or add a per-instance offset/scale attribute and use one instanced draw call.

The island outline is defined in three places. The terrain generator, the skin fragment shader, and PreviewSkinPass.draw each carry their own copy of the radius 215 and of the wobble formula sin(angle * 4) * 5 + cos(angle * 6) * 3. If one copy changes, the skin mask stops matching the coastline.

handlePan creates a new listener on every render.

handlePan(0, -1) returns a fresh function each time render() runs. Lit compares listener identity, so it removes and re-adds each D-Pad listener on every update.

Extract the shared trail attribute mapping.

The four blocks for nukeTrail, transportShipTrail, warship, and structures repeat the same three lines for movementSpeed, frequency, and colorSize. A new attribute variant will need four edits.

Add one small helper and spread it, which also keeps the mode-specific fields easy to read.

+    frequency: attrs.type === "transition" ? attrs.frequency : undefined,
+    colorSize: attrs.type === "gradient" ? attrs.colorSize : undefined,
+  };

The ResizeObserver adds no behavior.

render() already compares clientWidth/clientHeight against the canvas backing size on every frame and resizes the camera. The rAF loop calls render() every frame. So this observer only triggers one extra render per resize event.

Inline comments:
In `@src/client/components/cosmetics/CosmeticRenderCanvas.ts`:
- Around line 264-269: Remove the direct renderer.setSalvoMode call from
handleToggleSalvo and rely on the updated() lifecycle handling triggered by
changing salvoEnabled, preserving the existing toggle and event-prevention
behavior.
- Around line 142-153: Update applyCosmetic so non-empty customColors are
assigned to config.effectColors for every cosmetic mode, removing the
config.mode === "SKIN" restriction while preserving the existing resolved/config
guards and salvoMode assignment.
- Around line 414-418: Update the class list in CosmeticRenderCanvas.render() to
replace focus:outline-none with focus:outline-hidden, preserving the focusable
div’s forced-colors focus indicator.

In `@src/client/render/gl/passes/fx-pass/FxSpritePass.ts`:
- Around line 284-321: Add a disposed-state flag to the FxSpritePass lifecycle,
set it in dispose(), and in loadAtlas() return immediately after await
img.decode() when the pass has been disposed, before accessing WebGL resources
or setting atlasReady.

Apply the same fix in `@src/client/render/gl/passes/fx-pass/FxSpritePass.ts`
around lines 286 - 288.

In `@src/client/render/preview/CosmeticPreviewRenderer.ts`:
- Around line 277-286: Update the spiralParams guard in CosmeticPreviewRenderer
so it accepts both NUKE_MISSILE_TRAIL and MIRV_CLUSTER modes when spiralRadius
is defined, preserving the existing parameter defaults and color handling.
- Around line 303-318: Update setPreviewColors to re-run setCosmetic after
storing the new effectColors, matching the existing setSalvoMode pattern so
spiralParams.colors and the ticker receive the selected colors while preserving
the current preview behavior. If setCosmetic resets the camera preset, separate
that reset before reusing it so changing colors does not alter the current
camera.

In `@src/client/render/preview/passes/PreviewSkinPass.ts`:
- Around line 149-171: Update PreviewSkinPass.setSkinUrl to use an isDisposed
guard and a monotonically changing load token so callbacks after dispose or
superseded setSkinUrl calls are ignored; add image error handling that reports
the failure and preserves hasSkin as false. Reset texture state and delete the
WebGL texture in dispose, and add the same isDisposed early return to setPattern
before any texture upload.

In `@src/client/Store.ts`:
- Around line 83-87: Update StoreModal’s open-cosmetic-preview listener to use a
stable handler field, then remove that exact handler in disconnectedCallback()
so reconnecting does not accumulate listeners or trigger repeated updates.

In `@src/client/WebGLFrameBuilder.ts`:
- Around line 106-112: Remove the adapter-level thickness and density defaults
in WebGLFrameBuilder, leaving those parameters optional so FxShockwavePass can
resolve them from RenderSettings; retain transitionSpeed handling. In
src/client/WebGLFrameBuilder.ts lines 106-112, update the returned params
accordingly. In src/client/render/gl/passes/fx-pass/FxShockwavePass.ts line 217,
keep thickness defaulting there and use nullish coalescing so a configured width
of 0 is preserved.

In `@tests/CosmeticPreviewRenderer.test.ts`:
- Around line 102-106: Remove the conditional guard around the warhead
assertions in the ticker sampling test, and assert directly that
warheadSnapshot.units has length 8 and that its first unitType is "MIRV
Warhead".

---

Nitpick comments:
In `@src/client/components/cosmetics/CosmeticRenderCanvas.ts`:
- Around line 247-255: Update CosmeticRenderCanvas so the four D-Pad pan
callbacks are created once as class fields using handlePan, then bind those
stable handler fields in the template instead of calling handlePan during
render; keep handlePan’s pan behavior unchanged.
- Around line 331-382: Add a small shared helper near the effect-mapping logic
that derives movementSpeed, frequency, and colorSize from trail attributes, then
spread its result into the nukeTrail, transportShipTrail, warship, and
structures return objects. Remove the duplicated conditional mappings while
preserving each block’s existing mode-specific fields.
- Around line 109-119: Remove the redundant resize-observer path: delete
setupResizeObserver, the resizeObs field and initialization/cleanup, and any
calls to setupResizeObserver in CosmeticRenderCanvas. Preserve the existing
animation-frame render loop and its client-size/backing-size resize handling.
- Around line 66-78: Update CosmeticRenderCanvas’s renderer failure handling to
set a failure state when CosmeticPreviewRenderer initialization throws, and
render a short fallback message through translateText() instead of leaving the
canvas blank. Add the corresponding English translation entry in the language
resources, and preserve the existing successful rendering path.
- Around line 327-329: Replace the name-based MIRV detection in
CosmeticRenderCanvas with a typed preview variant field on the nuke-trail
attributes, and use that field to select the MIRV preview explicitly. Preserve
the existing fallback behavior, wrapping it in Boolean(...) so the resulting
value is strictly boolean, and update the relevant attribute type and producers
to provide the new field.

In `@src/client/render/gl/passes/fx-pass/FxShockwavePass.ts`:
- Around line 180-196: In the density handling within FxShockwavePass, compute
the defaulted and clamped density once before the sparkles/embers type branch,
then reuse that value for both cell calculations while preserving the existing
bounds and fallback behavior.

In `@src/client/render/preview/CosmeticPreviewRenderer.ts`:
- Around line 242-245: Extract the repeated hex-to-normalized-RGB mapping into a
private toRgb01 method on CosmeticPreviewRenderer, preserving the fallback color
and normalization behavior, then replace the duplicate logic in the current
block, setPreviewColors, and updateEffectTexture with calls to that method.
- Around line 538-546: Update CosmeticPreviewRenderer so updateEffectTexture
reuses a Float32Array allocated once during construction, sized to width *
height * 4; call fill(0) at the start of updateEffectTexture before writing the
current effect colors, and remove the per-call allocation.
- Around line 258-269: Extract the shared explosion-duration calculation,
including the 0.001 speed floor and 100/15,000 ms bounds, into an exported
helper in FxShockwavePass. Replace the duplicated calculation in both the FX
pass and CosmeticPreviewRenderer with that helper, converting milliseconds to
seconds only where the preview requires it.
- Around line 479-494: Update applyCameraPreset to derive the zoom exclusively
from its preset input, using a single switch or equivalent mapping for
OPEN_OCEAN, COASTAL_BASEPLATE, and the applicable special-mode preset values,
then call setCameraState once with the selected zoom; do not read
this.currentMode in this method.
- Around line 159-211: Update both RendererConfig objects used by UnitPass and
StructurePass to include an empty players array. Narrow mockConfig to
Pick<Config, "msPerTick"> and remove the unnecessary double casts while
preserving the existing msPerTick behavior.

In `@src/client/render/preview/passes/PreviewExplosionPass.ts`:
- Around line 151-173: Optimize PreviewExplosionPass.draw by rendering each
explosion’s bounded quad instead of the full map quad, using the existing exp
center and radius to constrain fragment coverage while preserving the current
filtering and visual output. Update the relevant vertex geometry or uniforms and
draw setup; an instanced path is optional but not required.

In `@src/client/render/preview/passes/PreviewSkinPass.ts`:
- Line 105: Remove the unused uSecondaryColor uniform from PreviewSkinPass,
including its field declaration, getUniformLocation lookup, and upload; leave
secondaryColor only if it is still required elsewhere.

In `@src/client/render/preview/PreviewAnimationTicker.ts`:
- Line 92: Remove the unused hasDetonatedInCycle field from
PreviewAnimationTicker and delete its assignments in sampleNuke and sampleMIRV;
retain the existing Set-based detonation tracking unchanged.
- Around line 398-404: Derive maxDist from MIRV_WARHEAD_TARGETS and pApex
instead of using the hardcoded 154.2 value, selecting the greatest distance to
any target; keep getHitTime’s existing timing calculation unchanged.
- Around line 237-265: Reduce per-frame allocations in the trail-building logic
around the sampled trail loop and the analogous MIRV paths by reusing
preallocated typed or parallel arrays, or caching static apex-to-target path
data and updating only visible length. Replace per-pixel trail object creation
and push operations while preserving the existing coordinates, timestamps,
ordering, and rendering behavior for all targets.

In `@src/client/render/preview/PreviewMapGenerator.ts`:
- Around line 100-114: Centralize the island outline constants so all render
paths remain synchronized: in src/client/render/preview/PreviewMapGenerator.ts
lines 100-114, export shared radius and wobble-coefficient symbols and use them
in buildContinentalArchipelago; in
src/client/render/preview/passes/PreviewSkinPass.ts lines 54-56, source the
shader wobble coefficients from those exports rather than literals; and in lines
263-271, use the exported radius instead of 215 for uRadius.

Inline comments:
In `@src/client/render/gl/passes/fx-pass/FxShockwavePass.ts`:
- Around line 100-105: Store the quadVbo created during FxShockwavePass
initialization as an instance field, then update dispose() to delete it with the
WebGL context in addition to the existing VAO cleanup. Keep the buffer reference
available until disposal so repeated pass creation releases all GPU resources.

In `@src/client/render/preview/passes/PreviewSkinPass.ts`:
- Around line 265-270: Update setPatternColors to increment loadToken before
changing hasSkin, isPattern, or isTeamMode, invalidating any pending setSkinUrl
image callbacks so they cannot restore the previous skin over the fallback-color
preview.

@JB940 Yes. I checked the current CodeRabbit review threads on #5008.

All 12 CodeRabbit findings are resolved. This includes the previous nitpicks for tests, accessibility focus styling, listener cleanup, async image-load cleanup, GPU-buffer disposal, and preview color propagation.

The latest CodeRabbit review also reports no new actionable comments.

The older PR summary still shows pre-merge warnings. Those warnings are not unresolved CodeRabbit review threads.
