Generated documentation previously used generic Bootstrap styling. This change applies the Fast Forward documentation design system: the approved fox signature, Dash reading companion, navy navigation, purple active states, accessible light/navy theme control, code windows and copy controls, responsive guide outlines and nested reading anchors.

Existing Twig/Bootstrap integration, guide/API destinations, Fuse search and UML hooks remain compatible. Runtime identity images are copied from data/ into generated sites. DESIGN.md links the canonical php-fast-forward/.github source of truth.

Validation:

  • Real root/nested guide and API generation with phpDocumentor 3.10.0 on PHP 8.3, 8.4 and 8.5.
  • PHP DOM verification of 14 pages, reading anchors, theme controls, unchanged examples and source bytes, and byte-identical copied identity assets.
  • The same generation and verification from a Git archive on all supported PHP versions.
  • Composer strict validation, PHP syntax, actionlint and diff checks.
  • Previously completed browser validation of theme persistence, exact code copying, source-line navigation, search and a 390px mobile viewport; the final CI/README additions do not change that rendering implementation.

The official phpDocumentor shim is a development-only Composer tool; its signed PHAR is installed through its specifically allowed plugin. Consumers gain no new runtime package requirement. Bundled PHAR dependencies are outside Composer's audit coverage, so documentation generation uses trusted project sources.

Merged as 2113cf2. Release v2.1.0 was published after the companion archive cleanup PR #5; its tag points to 1005b52.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Refreshed documentation pages with Fast Forward styling, updated navigation and search, and clearer code examples.
    • Added a light/dark reading theme that remembers your preference, plus code-copy controls when supported by your browser.
    • Added “On this page” navigation for guides, a skip link to main content, collapsible mobile navigation, and improved navigation labels and active-page indicators.
  • Documentation
    • Added a design guide and expanded the README with an overview of the documentation experience.

Walkthrough

The template updates the generated documentation layout and visual system. It adds theme, guide-outline, responsive-navigation, and code-copy behavior. It copies image assets into generated sites and adds fixture generation, output verification, and CI checks.

Changes

Documentation template refresh

Layer / File(s) Summary
Visual system and generated assets
css/base.css.twig, template.xml, README.md, DESIGN.md, CHANGELOG.md
The stylesheet adds theme tokens, documentation component styling, responsive and print rules, and reduced-motion overrides. The template copies two image assets. The README, design guide, and changelog document the design and release.
Page shell and navigation
layout.html.twig, components/header.html.twig, components/menu.html.twig, components/search.html.twig, guides/structure/document.html.twig, index.html.twig
The templates update the header, search, menu accessibility, article structure, and guide-outline rendering. They add document-relative reading links and a mobile navigation disclosure.
Reading and code controls
js/template.js.twig, components/source-modal.html.twig
The script builds guide-outline links, manages theme preference and responsive navigation, and adds titled code toolbars. It adds a copy control when secure-context clipboard writing is available. Loaded source code can trigger highlighting, code enhancement, and line positioning.
Fixture generation and output checks
composer.json, tests/fixture/phpdoc.xml, tests/fixture/docs/*, tests/fixture/src/Example.php, tests/generate-fixture.php, tests/verify-output.php, .github/workflows/tests.yml
The fixture defines phpDocumentor inputs, guide content, and an API example. The generator builds fixture output, and the verifier checks pages, links, assets, controls, and code samples. CI tests checkout and archive builds across PHP versions and runs actionlint.

Merge Risk: 🔵 Low · up to 3c489

The design-pattern link should be repaired, but it does not block use of the template. The previously identified print-color and source-highlighting risks are addressed.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to 22be2

The new controls remain within generated documentation pages and browser-managed capabilities. Theme persistence stores only a presentation preference, and copying requires user interaction and browser clipboard access. No material security risk was identified in these changes.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The new controls propagate through pages loading the shared template script. Their mutable scope is the current document, an origin-wide cosmetic preference, and the user's clipboard following an explicit copy action; the inspected paths do not introduce server-side identity or datastore authority.

Trust Boundaries and Controls

  • observed — Content-derived heading and code-title labels use textContent rather than HTML insertion. Clipboard writes occur in click handlers and remain subject to browser secure-context and permission controls; the feature neither executes copied examples nor reads clipboard contents.

Resilience and Maintainability Implications

  • inferred — Cross-tab theme changes need not converge until reload, and overlapping clipboard requests can reorder status messages and timers. These limitations affect presentation feedback, not authorization, stored sensitive data, or clipboard permission enforcement.

A rabbit reads beneath the moon,
Then flips the theme from dusk to noon.
It copies code with one quick tap,
And finds each heading on the map.
The pages bloom with guides to share,
While Dash hops through the sample there.

Addressed the docstring-coverage finding from #4 (comment) in ef5dd0b: the four verifier helpers now describe their contracts and path-resolution behavior. All five PHP functions across the verifier and fixture Example class have docblocks. PHP syntax validation and the real 14-page phpDocumentor fixture verifier pass; I have not claimed a refreshed CodeRabbit coverage score.

layout.html.twig:30-35
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep the base URL at the current page.

For a nested page hosted under a URL prefix, path() already adjusts asset URLs for page depth. The additional depth in baseHref makes those URLs resolve outside the prefix. Keep baseHref at ./ and let path() handle the depth adjustment.

Suggested fix
-    {% set destinationDepth = normalizedDestination ? (normalizedDestination|split('/')|length - 1) : 0 %}
     {% set currentDocumentHref = normalizedDestination ends with '.html' ? normalizedDestination : (normalizedDestination ? normalizedDestination ~ '.html' : 'index.html') %}
     {% set baseHref = './' %}
 
-    {% if destinationDepth > 0 %}
-        {% set baseSegments = [] %}
-        {% for i in 1..destinationDepth %}
-            {% set baseSegments = baseSegments|merge(['../']) %}
-        {% endfor %}
