# Platform Guides

Platform Guides own bounded comparison with named platform conventions and their version, authority, adaptation, and freshness limits.

## Scope Boundary

In scope: comparative vocabulary, interaction questions, current official-source requirements, and locally verified adaptation notes.

Out of scope: affiliation, brand imitation, unsupported platform equivalence, and authority over web standards, accessibility, or Layout contracts.

| Task                                                  | Route                                                                                                                        |

| Record native facts, target decisions, and fallbacks. | [Platform Adaptation Workflow](https://style.gallery/library/platform-guides/adaptation-workflow/index.md)                   |
| Compare Back and adaptive window behavior.            | [Android Interaction As A Comparative Reference](https://style.gallery/library/platform-guides/android-interaction/index.md) |
| Compare keyboard, focus, and commands.                | [Windows Interaction As A Comparative Reference](https://style.gallery/library/platform-guides/windows-interaction/index.md) |
| Select target and fallback verification cases.        | [Platform Compatibility Matrix](https://style.gallery/library/platform-guides/compatibility-matrix/index.md)                 |

These workflows and worked cases are usable experimental guidance. Expected-result tables are test designs; actual product, engine, and reader evidence must be recorded separately. Review on a failed task, a source change, or a changed ownership contract.

## Available Guides

- [Apple Interaction As A Comparative Reference](https://style.gallery/library/platform-guides/apple-interaction/index.md) turns selected interaction themes into questions for web adaptation without claiming platform equivalence.

## Comparison, Not Imitation

A platform guide names the platform, source authority, version or review date, web-adaptation boundary, and local verification protocol. Similar appearance or behavior does not establish affiliation or correctness.

## Source-Backed Deep Dives

- [Adaptive Navigation Across Platforms](https://style.gallery/library/platform-guides/adaptive-navigation/index.md). Preserve task state across window and navigation transformations.
- [Preferences And Accessibility Across Platforms](https://style.gallery/library/platform-guides/preferences-and-accessibility/index.md). Compare text scaling, contrast, motion, and transparency independently.
- [Input And Focus Across Platforms](https://style.gallery/library/platform-guides/input-and-focus/index.md). Compare keyboard, pointer, drag alternatives, and focus contracts.

## Domain Contract

See [StyleGallery Domains](https://style.gallery/materials/v2/pages/DOMAINS.md) for lifecycle, provenance, page membership, and staleness rules.
