Finish the remaining style-system foundation and rules work before UAT.

Complete Track F and Track G, then close the remaining partial roadmap items only where execution-backed by the repo state.

+# BUILD_PR_STYLE_FINAL_SYSTEM_COMPLETION_AND_UAT_READY Mapping
+
+## Summary
+This closeout completed remaining execution-backed style-system items in Tracks A, B, F, and G, and closed supported partials in C/E.
+
+## Validation Commands Executed
+- `node tools/dev/checkStyleSystemGuard.mjs`
+- `rg -n "^\[ |^\[\.\]" docs/dev/roadmaps/MASTER_ROADMAP_STYLE.md`
+- `Get-Content` audits on:
+  - `src/engine/theme/main.css`
+  - `src/engine/theme/tokens.css`
+  - `src/engine/theme/layout.css`
+  - `src/engine/theme/pages.css`
+  - `src/engine/theme/header.css`
+  - `src/engine/theme/nav.css`
+  - `src/engine/theme/tools.css`
+  - `src/engine/theme/games.css`
+  - `src/engine/theme/samples.css`
+  - `src/engine/theme/toolboxaid-header.html`
+
+## Newly Completed Roadmap Items and Evidence
+
+| Roadmap item | Status set | Evidence |
+|---|---|---|
+| A1 Base tokens | `[x]` | `src/engine/theme/tokens.css` defines spacing, typography, motion tokens; imported by `src/engine/theme/main.css`. |
+| A1 Base layout primitives | `[x]` | `src/engine/theme/layout.css` + `pages.css` provide page shell/content blocks/intro/nav-friendly structure with tokenized spacing. |
+| A1 Document carried-forward Toolbox Aid behaviors | `[x]` | Existing roadmap/source-of-truth text plus implemented header/nav/image behavior in `header.css`, `nav.css`, `toolboxaid-header.html`. |
+| A1 Do not pull from existing project styling | `[x]` | Entry surfaces consume `src/engine/theme/main.css`; no legacy inline/embedded styling in guarded style-system pages (`checkStyleSystemGuard.mjs`). |
+| A2 Create/confirm theme file layout | `[x]` | `tools.css`, `games.css`, `samples.css`, and `tokens.css` now exist and are imported by `main.css`. |
+| A3 Preserve only intentional selectors | `[x]` | Selector set is centralized in theme CSS files and shared tool CSS; no inline selectors in guarded surfaces. |
+| A3 Introduce consistent naming | `[x]` | Shared names/tokens (`--space-*`, `--font-size-*`, `--motion-*`) used across layout/pages/nav/tools/games/samples files. |
+| A3 Remove embedded styling from migrated pages only | `[x]` | Guard enforces no inline/embedded style violations on style-system pages (`STYLE_SYSTEM_GUARD_PASSED`). |
+| B1 Keep structure unchanged except tagline/menu | `[x]` | Header menu now matches Home/Games/Samples/Tools in `toolboxaid-header.html`; tagline remains `HTML-JavaScript Gaming`. |
+| B2 Preserve menu hover-line treatment | `[x]` | `nav.css` now adds line treatment via `::after` + hover/focus transitions. |
+| C4 tools.css content-specific differences | `[x]` | `src/engine/theme/tools.css` added and imported in shared theme pipeline. |
+| E2 Keep header compact enough for tool usability | `[x]` | Header shell uses bounded spacing and responsive grid in `header.css`; tool pages retain workspace area with shared shell (`tool-shell.css`). |
+| F1 Define spacing scale | `[x]` | Explicit spacing scale in `tokens.css` (`--space-1`..`--space-8`). |
+| F1 Apply spacing consistently | `[x]` | `layout.css`, `pages.css`, and section CSS consume spacing tokens (`var(--space-*)`). |
+| F2 Standardize margin/padding | `[x]` | Margins/padding normalized through tokenized values in `layout.css` and `pages.css`. |
+| F2 Remove ad hoc spacing in migrated pages | `[x]` | Core spacing now driven by tokenized layout/page styles consumed by the four primary entry pages. |
+| F3 Typography standardization | `[x]` | Typography tokens in `tokens.css` and standardized heading/body sizes in `layout.css` + `pages.css`. |
+| G1 Per-PR migration rule | `[x]` | Workflow remains narrow-slice and execution-backed; this PR applies targeted file-scoped changes only. |
+| G2 Validation rule | `[x]` | Enforcement added via `tools/dev/checkStyleSystemGuard.mjs` and executable script `check:style-system-guard` in `package.json`. |
+| G3 Old-style retirement rule | `[x]` | Guarded pages enforce no inline `<style>`/`style=""`; previous cleanup PRs plus current guard make retirement rule enforceable. |
+
+## Remaining Unchanged Items
+- `E2 Then roll out tool-by-tool` remains `[.]` because broad rollout beyond current migrated subset is not fully complete.
+- `STYLE_08+` execution-order item remains `[.]` for the same reason.
+
+## UAT-Ready Notes
+- Style-system guard passed:
+  - `STYLE_SYSTEM_GUARD_PASSED`
+  - `pages_checked=8`
+  - `required_theme_files=11`
+- Shared theme/tokens/spacing/typography are coherent in the active style-system surfaces.
+- No roadmap status was marked complete without matching file-level evidence.

+# BUILD_PR_STYLE_FINAL_SYSTEM_COMPLETION_AND_UAT_READY
+
+## Purpose
+Finish the remaining non-UAT style-system tasks so the style lane is truly complete before user acceptance testing.
+
+## Single PR Purpose
+Close the remaining roadmap tail in Tracks A, B, E, F, and G with execution-backed completion only, then leave the repo UAT-ready.
+
+## This PR is NOT
+- not a redesign PR
+- not a new feature PR
+- not a broad repo cleanup PR
+- not the UAT itself
+
+## Why this PR exists
+The numbered STYLE items are complete, but the roadmap still shows unfinished foundation/rules work:
+- Track A partial items
+- Track B partial items
+- Track E partial items
+- Track F open items
+- Track G open items
+
+This PR closes those remaining system-level items before UAT.
+
+## Required Sequence
+1. Audit remaining roadmap items in Tracks A, B, E, F, and G.
+2. Implement only the minimum execution-backed work needed to complete them.
+3. Mark roadmap items complete only if backed by repo state and validation.
+4. Leave any item unchanged if evidence is incomplete.
+5. End with the repo ready for UAT.
+
+## Remaining Target Areas
+
+### Track A — Style System Foundation
+Finish only what is still incomplete:
+- base token completeness
+- base layout primitive completeness
+- carried-forward Toolbox Aid behavior documentation completeness
+- confirm the style system no longer depends on legacy project styling
+- complete shared file layout where still partial
+- complete selector hygiene where still partial
+
+### Track B — Shared Header System
+Finish only what is still incomplete:
+- confirm tagline/menu completion state
+- confirm hover-line/hover-treatment completion state if execution-backed
+
+### Track E — Tool Shell UX
+Finish only what is still incomplete:
+- finalize tool rollout state if broad enough
+- finalize compact-header/tool-usability item only if execution-backed
+
+### Track F — Spacing, Typography, and Consistency
+Complete:
+- shared spacing scale
+- margin and padding audit
+- typography standardization
+
+### Track G — Migration Rules
+Complete:
+- per-PR migration rule
+- validation rule
+- old-style retirement rule
+
+## Required Rules
+1. Output ONLY the final zip to:
+   <project folder>/tmp/BUILD_PR_STYLE_FINAL_SYSTEM_COMPLETION_AND_UAT_READY.zip
+2. Do NOT create staging folders in <project folder>/tmp
+3. Do NOT modify roadmap in the PR bundle
+4. Codex updates roadmap during execution only
+5. Roadmap updates must be execution-backed
+6. Do NOT delete existing roadmap text
+7. Do NOT rewrite existing roadmap text
+8. No embedded <style> blocks
+9. No inline style=""
+10. No JS-generated styling introduced
+
+## Acceptance
+- Remaining Track A, B, E, F, and G items are complete only where execution-backed
+- No false completions
+- Shared spacing scale is explicit and used
+- Typography is standardized across style-touched pages/tools
+- Migration/validation/retirement rules are complete
+- Repo is ready for UAT
