Navigation Performance Optimization

Implemented a multi-phase SPA-like navigation system focused on reducing perceived and actual navigation latency:

• Performance marks (nav-start/nav-end) with Long Task observation.
• Overlapped fetch + exit transition; removed fixed artificial delays.
• In-memory HTML cache + pointerenter/focus prefetch (80ms debounce).
• Idempotent animations: single import + reinit only, heavy animation work deferred with requestIdleCallback fallback.
• Progressive enhancement using View Transitions API with custom CSS fallback transitions.
• Concurrency guard via AbortController preventing overlapping fetches and ignoring redundant same-path clicks.
• Class-based page-enter/page-exit transitions to avoid inline style thrash.
• Sanitation/helpers reducing duplicated DOM queries and origin checks.
• Diagnostic utilities: __navMetrics() (quick stats) and __navSummary() (median, p95, mean, heuristic cache hit ratio).

Enhancements (Post-Phases):

• Cache TTL & LRU: in-memory cache capped (NAV_CACHE_MAX_ENTRIES=20) with 5‑minute TTL (NAV_CACHE_TTL_MS). Expired or least‑recently used entries are evicted automatically.
• Opt‑out attribute: add data-no-spa on any <a> to force a full page load (skips interception & prefetch).
• Performance budgets: configurable runtime budgets with warnings when exceeded.

Runtime Diagnostics & APIs (open DevTools Console):

__navMetrics();        // Quick count/median/p95 summary
__navSummary();        // Collapsed console table summary
__navExport();         // Detailed per-navigation records (path, duration, cached, longTasks)
__setNavBudgets({      // Update performance budget thresholds
	warnMedian: 320,
	warnP95: 800,
	warnLongTasks: 2
});
// Current budgets available at window.__navBudgets

Performance Budgets (defaults):

• Median warning: 350ms
• P95 warning: 900ms
• Long Tasks per navigation: >3

When a threshold is exceeded a [nav-budget] warning logs with context.

Rollback: checkout a pre-optimization tag (create one before merging, e.g. git tag pre-nav-optimization) or remove SPA init & related instrumentation blocks in public/js/main.js.

Future Opportunities:

• Persist navigation metrics to a JSON artifact for CI diffing.
• Lighthouse CI integration with budgets (TBT, CLS, LCP targets).
• Add data-preload hint to elevate priority of specific prefetch routes.
• Service Worker layer for offline cache & stale‑while‑revalidate.
