Parses a Zerodha KITE holdings CSV entirely in the browser — no server uploads — then fires requests to fetch dividend yields, valuation ratios, beta, analyst consensus, and 52-week ranges for every holding automatically

Six analysis tabs (Overview, Holdings, Dividends, Fundamentals, Risk, Analyst) with color-coded thresholds and sortable tables; every cell is editable inline and updates P&L aggregates and charts in real time

Risk tab flags high-risk positions by comparing beta and debt-to-equity against configurable thresholds, with a 52-week range progress bar that instantly surfaces holdings drifting toward annual lows

Four compounding calculators (SIP, Lumpsum, Goal, CAGR) with synchronized slider and text inputs; Recharts stacked-area charts separate invested principal from market-generated returns over the full horizon

Imports a real Lighthouse JSON report and fits simulation curves to match the measured score exactly — every what-if change is a calibrated, deterministic prediction against your actual page, not a generic estimate

Scores all five Core Web Vitals (FCP, LCP, TBT, CLS, SI) via Lighthouse's log-normal curves and metric weights; simulates mobile (150 ms RTT, 200 KB/s, 4× CPU) and desktop profiles simultaneously

Network waterfall decomposes each resource into DNS, connection, SSL, TTFB, and transfer phases; TTFB is estimated from file size and bandwidth so small files show proportional download bars instead of inflated ones

Optimization roadmap ranks every fix by score gain with Easy / Medium / Hard effort labels; applying a suggestion patches the variation instantly — no code changes, no redeploy

Comparison mode shows up to four named variations side by side with best/worst highlighting per metric; work persists to IndexedDB with JSON export so calibrated baselines can be shared with teammates
