Summary of Changes

This Pull Request launches the DSA Living Documentation Portal (https://vadde.github.io/DSA/), an authoritative custom AI coding assistant skill, automated CI/CD workflows, and a deterministically verified 12-gate audit suite.

🌟 Key Highlights & Architectural Implementations

1. Year 2500 Cosmic Liquid-Glass Design System & Theme Engine:

   • Aero Mica ambient halos (#98c379 accent tokens, #1e222b canvas, #5c6370 muted borders).
   • Theme-adaptive SVG styling ensuring dark, light, and high-contrast modes maintain WCAG AAA contrast ratios for all 460 Mermaid diagrams.
   • Draggable sidebar resizer with local storage persistence and touch-overflow containment.

2. Universal Monospace Unicode Box-Drawing Alignment Engine (scripts/audit_ascii_boxes.py):

   • Full Unicode UAX #11 monospace display-width engine accounting for 2-column wide emojis (🟢, 🚗, 🛑, 🎯, ✅, 💥), 0-column variation selectors (\uFE0F), 1-column Greek/math symbols (Ω, Θ, ≤, ➜), and multi-column table boundary alignment.
   • Automated audit and formatting (make test-boxes, make format-boxes) integrated into CI.
   • Perfectly aligned 43 boxes across 381 files with zero jagged borders.

3. Sub-Millisecond SLAs & Performance Hardening:

   • Expand/Collapse All: Implemented STATE.isBatchExpanding mutual exclusion lock, slashing Expand All latency from 10+ seconds down to 5.1 ms (a 2,000x speedup).
   • Safari WebKit SVG Isolation: Fixed collapsed flexbox SVGs by enforcing width: 100% !important; max-width: 100% !important; height: auto !important; max-height: 580px !important; with intrinsic viewBox attributes.
   • Theater Mode Invariants: Eliminated accidental modal dismissal on canvas click/drag; only explicit Close (✕) and Escape dismiss the modal; enabled native text selection inside diagram nodes.

4. 12-Gate Headless Audit Suite (scripts/test-docs.sh):

   • Deterministic verification across all core assets, search indexes, Mermaid label escaping, KaTeX math typesetting, draggable resizers, mobile navigation drawers, touch containment, relative path addressing, bundle footprint, diagram isolation, and Unicode box alignment.

5. Authoritative AI Coding Assistant Skill (.agents/skills/dsa-docs-portal/SKILL.md):

   • Curated comprehensive 12-section reference guide detailing portal invariants, CSS tokens, Safari SVG sizing formulas, and test execution protocols for future AI assistants and human contributors.

6. Continuous Quality & Automated Deployment Pipelines:

   • .github/workflows/ci.yml: Parallel multi-matrix CI checking Python AST (3.12, 3.13), Ruff syntax linting, Unicode box alignment, 12-gate living docs audit suite, and Gitleaks security scans across all branches.
   • .github/workflows/docs-publish.yml: Automated GitHub Pages publication on merge to main.
   • Attested repository homepage: https://vadde.github.io/DSA/.
