PR_26176_005-tool-display-mode-single-line-layout Report

Scope Source

• Active request: finalize existing branch PR_26176_005-tool-display-mode-single-line-layout.
• Branch gate: current branch confirmed as PR_26176_005-tool-display-mode-single-line-layout; no PR_26176_006 or PR_26176_007 branch was created.
• Worktree review: modified and untracked files were reviewed; accidental/unneeded PR_26176_001 through PR_26176_004 untracked report artifacts were removed.
• Note: docs_build/dev/BUILD_PR.md still describes PR_26175_ALFA_047-theme-v2-svg-icon-registry, so the user prompt was treated as the operative BUILD scope for this PR.

Summary

• Updated the shared Tool Display Mode template so the <summary> directly owns the badge, tool name, character image, and fullscreen/exit-fullscreen icon in that order.
• Kept the fullscreen/exit-fullscreen theme icon as the final direct child of <summary>, gold, 2.6x the base layout icon, and anchored to the far right with margin-left: auto.
• Removed the old Tool Display Mode chevron, stacked body/identity/description layout, and rendered navigation row UI.
• Removed nav.tool-display-mode__navigation-row, Previous: {tool}, Next: {tool}, and CSS/JS used solely to render or populate that row.
• Normal mode now displays both shared platform banner placements, data-platform-banner-placement="header" and data-platform-banner-placement="footer".
• Fullscreen mode keeps the header-placement platform banner visible, including .platform-banner__inner and the Development Environment message.
• Fullscreen mode hides the footer-placement platform banner with data-platform-banner-placement="footer".
• Fullscreen mode hides the main site navigation container, .site-header > div.container.nav, including the brand/home navigation.
• Shared fullscreen CSS targets the banner placement attribute and does not target .platform-banner__inner.
• Fullscreen mode hides the character image, renders the badge at 64x64, centers the growing tool name, and keeps the exit icon anchored far right.
• Narrowed the focused Playwright validation to Tool Display Mode behavior only and renamed it to ToolDisplayModeSingleLineLayout.spec.mjs.
• Removed older PR_26176_001/002 validation assertions and style changes for horizontal accordion color and footer status icon sizing from this branch.

Validation

• node --check assets/theme-v2/js/tool-display-mode.js
• node --check tests/playwright/tools/ToolDisplayModeSingleLineLayout.spec.mjs
• npx playwright test tests/playwright/tools/ToolDisplayModeSingleLineLayout.spec.mjs --workers=1
• git diff --check

Notes

• No individual toolbox pages were modified.
• The previous fullscreen rule that hid .platform-banner__inner was removed.
• No PR_26176_006 or PR_26176_007 branch/artifact was created during this finalization pass.
• Game Journey completion metrics SQLite/Postgres behavior was not changed; that warning is documented as Golf-owned external storage migration work outside this PR.
• The focused Playwright run uses deterministic route fixtures for public config, platform banner settings, registry metadata, game-design constants, and minimal game-design repository calls.

Closed as replaced by PR #254 (PR_26179_ALFA_010-tool-display-single-line-summary), which recreated the useful Tool Display Mode single-line summary scope on current main.
