Landing page rebuilt around a single interactive, multi-range price chart and served directly
from FastAPI with server-rendered live data, replacing the earlier React portfolio-tracker
prototype.

Added

  • web/index.html — self-contained landing page built around a single interactive price chart:
    metal selector (gold/silver/platinum/palladium), preset and custom date ranges, a USD/₹ unit
    toggle, permanent x/y axis labels with gridlines, and a speech-bubble-style hover readout showing
    the price and date for any point on the line.
  • api.py — /api/metals, /api/prices/{metal}, /api/fx/{currency}, and /api/widget/{metal}
    HTTP endpoints serving data from the SQLite store.
  • GET /api/prices/{metal} accepts start/end date-range params (uncapped) alongside the capped
    days window, powering the landing page's full-history range picker (1W through ALL).
  • GET /api/fx/{currency} — daily FX rate history (uncapped start/end), so the site can convert
    the full price history to INR using each day's actual rate instead of one approximated rate.
  • GET / is now a proper FastAPI route (Jinja2, api.py's _latest_meta) instead of a static file:
    the hero ingot's price, batch date, "last update" date, and the trust-strip's day count are
    computed straight from the database at request time, so the page never carries a placeholder
    value for them.
  • web/assets/style.css, web/assets/script.js, web/assets/hero-preview.png — the page's CSS,
    JS, and hero screenshot, previously inlined into index.html (including as base64 data URIs for
    fonts and the hero image), extracted into their own linked files. Cut index.html from ~210KB to
    ~44KB.
  • render.yaml for deploying the API to Render.

Changed

  • Locked /api/metals, /api/prices, and /api/fx to same-origin requests.
  • INR prices now use the real daily USD→INR rate for each date, instead of a single rate derived
    from the latest day and applied across the whole history.
  • index.html now declares a proper <!DOCTYPE html>/<html>/<head>/<body> document structure
    with a charset and viewport meta tag, instead of a bare fragment with neither — the missing
    viewport tag meant mobile browsers were rendering the page at desktop width and scaling it down.

Removed

  • frontend/ — the React + Vite portfolio tracking tool (buy/sell logging, CSV import/export against
    spot price) and its built output web/portfolio/, along with the inline modal used to open it from
    the landing page and the GET /api/prices/{metal}/on/{on_date} endpoint that only existed to
    support it. Simplifies the product surface for the current go-to-market plan.

Fixed

  • Added UNIQUE constraints on schema tables and reused init_db in tests to prevent duplicate rows.
