src/client/HostLobbyModal.ts (1)
248-255: Implementation works correctly.The disabled state for difficulty selection when nations are disabled is properly implemented with clear visual feedback (reduced opacity and cursor change) and a guarded click handler.
Optional: Consider adding semantic accessibility and cleaner styling
1. Accessibility enhancement: Add
aria-disabledattribute to help screen readers:<div class="option-card ${this.selectedDifficulty === value ? "selected" : ""}" style="opacity: ${this.disableNations ? "0.3" : "1"}; cursor: ${this.disableNations ? "not-allowed" : "pointer"};" + aria-disabled="${this.disableNations}" @click=${() => !this.disableNations && this.handleDifficultySelection(value)} >2. Code style improvement: Consider using conditional class binding for cleaner code:
Add CSS classes:
.option-card.disabled { opacity: 0.3; cursor: not-allowed; }Then simplify the template:
<div - class="option-card ${this.selectedDifficulty === value - ? "selected" - : ""}" - style="opacity: ${this.disableNations - ? "0.3" - : "1"}; cursor: ${this.disableNations - ? "not-allowed" - : "pointer"};" + class="option-card ${this.selectedDifficulty === value ? "selected" : ""} ${this.disableNations ? "disabled" : ""}" + aria-disabled="${this.disableNations}" @click=${() => !this.disableNations && this.handleDifficultySelection(value)} >src/client/SinglePlayerModal.ts (1)
151-158: Consistent implementation, works correctly.The disabled state logic here matches the implementation in HostLobbyModal.ts, which is good for consistency. The visual feedback and click handler guard work as intended.
The same optional accessibility and code style improvements suggested for HostLobbyModal.ts (Lines 248-255) would apply here:
- Add
aria-disabled="${this.disableNations}"for screen reader support- Consider using conditional CSS classes instead of inline styles for cleaner code

Learning: For OpenFrontIO project: When localization keys are renamed in language JSON files, the maintainers separate technical changes from translation content updates. They wait for community translators to update the actual translation values rather than attempting to translate in the same PR. This allows technical changes to proceed while ensuring accurate translations from native speakers.

Learning: In OpenFrontIO, nation names in map manifests are displayed directly in the UI without translation. They do not need to be added to resources/lang/en.json or processed through translateText(). This is the established pattern across all existing maps including Europe, World, Asia, Africa, and others.

Learning: For the HumansVsNations game mode in `src/client/HostLobbyModal.ts` and related files, the implementation strategy is to generate all nations and adjust their strength for balancing, rather than limiting lobby size based on the number of available nations on the map.

Learning: In OpenFrontIO, some country entries in src/client/data/countries.json may have similar names but different codes (e.g., "Empire of Japan" vs "Empire of Japan1"). Each unique code requires its own translation key in resources/lang/en.json after normalization. Always verify against countries.json before suggesting removal of translation keys.

Learning: In src/client/Main.ts, during game start in the handleJoinLobby callback, UI elements are hidden using direct DOM manipulation with classList.add("hidden") for consistency. This includes modals, buttons, and error divs. The codebase follows this pattern rather than using component APIs for hiding elements during game transitions.

347-347: LGTM! Clear label improvement.The label change from "Difficulty" to "Nation difficulty" effectively clarifies that this setting only affects nations, which improves user understanding.

147-163: Disabled state implementation looks good.The logic correctly prevents difficulty selection when nations are disabled by using short-circuit evaluation in the click handler. The visual styling via the "disabled" class and
aria-disabledattribute provide clear feedback to users and screen readers.Optional: Enhance keyboard accessibility
Currently, disabled cards remain keyboard-focusable. Users can still tab to them and press Enter/Space, though the click handler won't fire. For better accessibility, consider making disabled cards non-focusable:
([key, value]) => html` <div class="option-card ${this.selectedDifficulty === value ? "selected" : ""} ${this.disableNations ? "disabled" : ""}" aria-disabled="${this.disableNations}" + tabindex="${this.disableNations ? "-1" : "0"}" @click=${() => !this.disableNations && this.handleDifficultySelection(value)} >This prevents keyboard users from reaching non-functional elements.

110-117: Text wrapping improvement works well.Adding word-break and overflow-wrap ensures long option titles wrap properly within their cards, improving the layout.
Optional: Simplify property usage
Both
word-break: break-wordandoverflow-wrap: break-wordare present. Sinceoverflow-wrapis the standard property that handles this, you could simplify to just use that one:.option-card-title { font-size: 14px; color: #aaa; text-align: center; margin: 0 0 4px 0; - word-break: break-word; overflow-wrap: break-word; }Keeping both provides extra compatibility but isn't strictly necessary.
