Stacked on #4243 (the `perf:client` harness) — first step of fixing the
every-100ms main-thread stutter: make the per-tick burst small before
spreading what remains across frames.
## Problem
The harness showed the main-thread burst was dominated by
`structuredClone` of the `updates` object, and the clone was dominated
by two kinds of per-tick churn that re-sent object payloads every tick:
- `gold` / `troops` / `tilesOwned` change for nearly every alive player
every tick → ~278 partial `PlayerUpdate` objects per tick (world/400
bots), ~508 on giantworldmap.
- Attack troop counts tick down every tick → whole
`outgoingAttacks`/`incomingAttacks` arrays re-cloned for every fighting
player every tick.
- `playerNameViewData` (an all-players record) was cloned every tick but
only recomputed every 30 ticks.
## Change
Three additions to the worker → main protocol (all transferable,
zero-clone):
1. **`packedPlayerUpdates`** — `[smallID, tilesOwned, gold, troops]`
float64 quads for players whose stats changed. These fields no longer
appear in `PlayerUpdate` diffs (first emissions still carry the full
snapshot). Gold is exact in a float64 (game values ≪ 2^53).
2. **`packedAttackUpdates`** — `[ownerSmallID, direction, index,
troops]` quads. Attack arrays are only resent when
membership/order/retreating changes — which is exactly the condition
that keeps the patch indexes valid (a tick either resends an array or
patches it, never both).
3. **`playerNameViewData` is now optional** — attached only on
placement-rebuild ticks (spawn ticks, first ticks, every 30th, spawn
end). The client keeps the last applied values; dead players' name
placements freeze at death (matching the previous effective behavior).
On the client, `GameView.populateFrame` now also rebuilds `names` /
`relationMatrix` / `allianceClusters` only when their inputs changed
that tick — field presence on a partial `PlayerUpdate` marks them dirty.
(`playerStatus`, nuke telegraphs, and attack rings still recompute every
tick; they're tick- or unit-dependent.)
## Results (perf:client, this machine; low-end devices ~5–20× slower)
Default run (world, 400 bots, 1800 ticks):
| stage | before | after |
|---|---|---|
| clone (serialize+deserialize) | 1.02ms | **0.09ms** |
| GameView.update | 0.62ms | **0.29ms** |
| WebGLFrameBuilder.update | 0.04ms | 0.04ms |
| **TOTAL burst mean** | **1.67ms** | **0.42ms** |
| TOTAL p99 / max | 3.47 / 10.3ms | **1.21 / 3.92ms** |
giantworldmap/600t: 2.54 → 0.68ms mean. Player update objects: 278 → 6.5
per tick (world), 508 → 12 (giant). The remaining burst is mostly tile
apply + per-tick derivations — the part that frame-spreading (next step)
addresses.
## Verification
- **Sim final hash unchanged** on all three reference configs
(`5607618202213430`, `29309648281599524`, `39945089450032050`) — no
simulation behavior change.
- **View hash unchanged** on all three configs (`942106e9`, `a3aae227`,
`cbaaf265`) — the rendered view state is provably identical
tick-for-tick, including the name-freeze semantics.
- New tests: `tests/PackedPlayerUpdates.test.ts` (drain + GameRunner
cadence), packed-channel and freeze-at-death cases in
`tests/client/view/GameView.test.ts`, `packAttackTroopDeltas` unit tests
and updated diff contract in `tests/GameUpdateUtils.test.ts` /
`tests/PlayerUpdateDiff.test.ts`.
- `npm test` (1490 tests), `eslint`, `prettier`, `tsc --noEmit` all
pass.

**Add approved & assigned issue number here:**
N/A — maintainer refactor.
## Description:
Replaces the theme class hierarchy
(`BaseTheme`/`PastelTheme`/`ColorblindTheme`) with theme JSON files —
`default-theme.json` and `colorblind-theme.json` — combined with
`render-settings.json` at runtime into a single graphics-configuration
pipeline (`settings.theme`). One `SettingsTheme` class keeps the
algorithms (color allocation, team-variation generation, LAB-contrast
structure colors) and reads all data from `ThemeSettings`; adding a
theme is now just adding a JSON file.
Colorblind mode (#4150) is fully preserved:
- Same palettes — the 32-color CVD-safe pool and Okabe-Ito team colors
are baked into `colorblind-theme.json`
- The relative border rule (`l × 0.6`) is expressed as a
`borderLightnessScale` knob alongside the default theme's absolute
`borderDarken`
- The mid-game re-theme wiring (`refreshPlayerColors`/`refreshPalette`)
and the affiliation/friend-foe tint overrides are unchanged;
`applyGraphicsOverrides` now also swaps the `settings.theme` slice
- `deepAssign` replaces arrays wholesale so differing palette lengths
survive theme switches
Verified against the previous implementation with an equivalence test
(since removed): default-theme colors are byte-identical including
allocation order; colorblind team/derived colors are byte-identical, and
FFA assignment may permute within the same palette (hex baking rounds
upstream's fractional-RGB colord objects, which can flip the allocator's
greedy delta-E ordering — rendered colors round identically either way).
Also removes dead theme surface (`terrainColor`, `backgroundColor`,
`falloutColor`, `font`, `textColor`, spawn-highlight variants,
`PastelThemeDark`) — GL terrain colors and dark mode were already
handled in the renderer. Note this means the colorblind terrain bands
from #4150 were dead code (nothing calls `terrainColor`; GL terrain
comes from `ColorUtils.encodeTerrainTile`); wiring CVD-safe terrain into
the terrain texture would be a follow-up.
## Please complete the following:
- [x] I have added screenshots for all UI updates — N/A, no UI changes
(verified color-identical)
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file — N/A, no user-visible text
- [x] I have added relevant tests to the test directory —
`tests/Colors.test.ts` updated for the new pipeline (team colors from
theme JSON, colorblind palette/border tests)

Resolves#2549
## Description:
Themes are purely for the client's rendering, and the server doesn't
need context on them. This PR moves `Theme.ts` from
`src/core/configuration` to `src/client/theme` and moves affiliation
colors to `render-settings.json`.
This is to support the ability to add additional themes more quickly,
such as colorblind-friendly themes. No visible changes occur from this
refactor.

PlayerView/UnitView now wrap renderer-shaped state objects (PlayerState,
PlayerStatic, UnitState) directly instead of holding engine wire types.
GameView owns a long-lived FrameData object kept in sync each tick:
players/units/tiles/trail/railroad are mutated in place; derived buffers
(playerStatus, relationMatrix, allianceClusters, nukeTelegraphs,
attackRings) and events are recomputed in a final populateFrame() pass.
The renderer reads gameView.frameData() and the same byte-identical
state objects PlayerView/UnitView wrap. WebGLFrameBuilder shrinks from
~270 to ~70 LOC: palette management + a single uploadFrameData() call,
no per-frame UnitState allocation on the hot path.
Wiring: maxPlayers=1024 on RendererConfig (pre-sizes NamePass/palette/
relation matrix textures); NamePass disabled so HTML NameLayer remains
the only on-screen player names.
Also: 39 new tests covering PlayerView/GameView/FrameData behavior;
replace .data field access in three layer call sites with accessor
methods (betrayals(), type(), getTraitorRemainingTicks()).
