fix(ui): preserve widescreen card aspect ratios

[arazmj]

Summary

• Preserve the aspect ratio of command buttons, the selected-unit cameo and upgrades, and production queue buttons on displays wider than 4:3.
• Center the compact card groups inside their existing stretched HUD regions.
• Keep full-width control bar artwork and existing 4:3 behavior unchanged.

Root cause

The legacy window layout scales horizontal and vertical coordinates independently. At 3440x1440, that stretches card widths by a larger factor than their heights and visibly distorts unit and command artwork.

The new layout step recovers each card's logical horizontal geometry, reapplies the vertical scale uniformly to its width and spacing, and centers the resulting group within its existing parent window. The shared Core implementation applies to both Generals and Zero Hour and does not touch gameplay state.

Validation

• Built Zero Hour with ./scripts/build/macos/build-macos-zh.sh.
• Built Generals with ./scripts/build/macos/build-macos-generals.sh --build-only.
• Confirmed the corrected command cards and selected-unit cameo in a live 3440x1440 skirmish.
• Played a recorded multiplayer match through its previous frame-7404 synchronization checkpoint and to completion without a mismatch.

AI assistance

GitHub Copilot assisted with tracing the legacy UI scaling path, preparing the implementation, and drafting documentation. I reviewed and refined the focused diff, built both game targets, visually validated the layout, and replay-tested determinism before submission.

Summary by CodeRabbit

• Bug Fixes
  • Improved widescreen control-bar behavior by preventing purchase-science buttons from being horizontally stretched.
  • Preserved the existing widescreen scaling behavior for other control-bar elements.

📝 Walkthrough

Walkthrough

The control bar no longer horizontally aspect-scales purchase-science buttons during widescreen initialization. The dedicated center-preserving helper and related calls were removed. The worklog was updated to remove the corresponding center-preservation statement.

Control-bar purchase-science scaling removal

Layer / File(s)	Summary
Remove purchase-science widescreen scaling Core/GameEngine/Source/GameClient/GUI/ControlBar/ControlBar.cpp, docs/WORKLOG/2026-08-DIARY.md	Removes the center-preserving scaling helper and its calls for rank 1, rank 3, and rank 8 purchase-science button groups. Removes the related worklog statement.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 9d66d

The PR makes a localized UI layout adjustment and no actionable merge-blocking risk remains at the current head beyond normal checks and review.

Poem

Widescreen buttons stay in line,
The extra scaler fades away.
Rank groups keep their simpler path,
The worklog states the change today.
Clean layouts guide the display.

Full details: Title check

Explanation

The title follows Conventional Commits format with the valid type "fix", the scope "ui", and a descriptive summary. It accurately describes the pull request objective of preserving widescreen card aspect ratios.

Full details: Platform Isolation

Explanation

PASS: The PR changes only Core/GameEngine/Source/GameClient/GUI/ControlBar/ControlBar.cpp and the worklog. The added code uses the engine-level Display and GameWindow abstractions (TheDisplay, winGet*, and winSet*). It adds no Win32, Cocoa, raw POSIX, SDL, or DXVK API, header, or handle. No files under Generals/, GeneralsMD/, or Core/GameEngineDevice/ changed.

Full details: Cross-Platform Determinism

Explanation

PASS — The pull request changes only ControlBar.cpp UI layout code and a worklog. The added math runs in ControlBar::init() and initSpecialPowershortcutBar() and only computes display/window geometry. It does not update simulation or game state and uses no transcendental math that requires WWMath. The divisions use fixed nonzero display constants, and yScale / xScale executes only after xScale > yScale; with Display::getWidth() and getHeight() returning unsigned dimensions, these values remain finite before the integer casts.

Full details: Openal / Miniaudio Parity

Explanation

PASS: The pull request changes only ControlBar.cpp and docs/WORKLOG/2026-08-DIARY.md. The diff contains no OpenAL or MiniAudio changes. The OpenAL and MiniAudio manager, stream, and header files are unchanged, so backend parity is not affected.

Full details: Conventional Commit Standards

Explanation

All five commits in the PR range use valid Conventional Commit subjects, including fix(ui):, docs(ui):, and revert:. However, every complete commit message contains @ in the Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> trailer. This violates the explicit no-@ requirement.

Full details: Single Commit / Squash Policy

Explanation

The PR is not squashed. The merge base is bf982652 and the PR range contains five sequential commits: b3573d27, a5b957e7, f0b3c494, 8ca111d7, and 9d66d7ea. The commits are authored by Amir and contain UI implementation, documentation, and follow-up/revert changes. This is not an upstream sync PR from thesuperhackers, so the exception does not apply.
