Purpose and Scope

This document provides a comprehensive technical overview of the Yuuki Konno Personal Homepage System (yuuki15.github.io repository). The system implements a static personal homepage with multi-provider hosting redundancy, integrated external applications via Git submodules, and comprehensive personal profile data presentation.

The system serves as both a personal information portal and a platform for hosting interactive applications, with emphasis on high availability, content preservation, and international accessibility. For detailed information about specific subsystems, see Personal Profile System, Hosting & Infrastructure, Applications & Submodules, and Legal Framework & Licensing.

System Architecture Overview

The homepage system follows a distributed static web architecture with multiple hosting providers and integrated applications managed through Git submodules.

Git Submodule Integration

The system uses Git submodules to integrate external applications:

Submodule	Repository URL	Local Path	Purpose
flash	`https://github.com/yuuki15/flash.git`	`flash/`	Flash Add Game (フラッシュ暗算)
calc	`https://github.com/yuuki15/calc.git`	`calc/`	Calculator application
drawpoint	`https://github.com/yuuki15/drawpoint.git`	`drawpoint/`	Drawing application

The submodule configuration is managed through the .gitmodules file, enabling modular application development and independent versioning of each component.

Technical Implementation Details

HTML Document Structure

The main homepage (index.html) implements semantic HTML5 with specific technical characteristics:

Character encoding: UTF-8 with explicit <meta charset="utf-8"> declaration
Viewport configuration: Responsive design support via width=device-width, initial-scale=1
Color scheme support: Dark/light mode compatibility with content="light dark"
Canonical URL: SEO optimization with <link rel="canonical">
License integration: Creative Commons license reference via <link rel="license">

CSS Styling Strategy

The system uses minimal inline CSS for styling the personal data table:

#personal-data td,
#personal-data th {
  text-align: left;
  vertical-align: baseline;
}

This approach ensures consistent table formatting while maintaining lightweight page load performance.

Internationalization Implementation

The system supports bilingual content through proper HTML internationalization attributes:

Language declarations: lang="en" for document root, lang="ja" for Japanese content
Ruby annotations: Complex Japanese text with furigana using <ruby> and <rt> elements
Romanization: Latin transliteration with lang="ja-Latn" attributes
Cultural context: Appropriate abbreviations and cultural references
