Backend: GET /api/scan?symbols=SYM1,SYM2,... — for each symbol fetches
the front-expiry options chain plus 30-day realized vol and returns
{ spot, change, changePct, atmIv, hv30, ivHv, spike, expiry }. Spike flag
is on when IV/HV ≥ 1.5 or |today's % change| ≥ 3. Defaults to ~15 popular
tickers when no list is given; cap of 30 symbols/scan.
Frontend: new scanner.html page — symbol input (with "Use defaults" / "Use
watchlist" shortcuts), summary cards (count · spikes · biggest mover ·
highest IV/HV), sortable results table with spike rows highlighted, and
shortcut buttons to open each symbol on Chain or Surface.
Scanner added to all sidebars between Vol Surface and Strategy P/L.

Every page now uses the same brand logo (candle chart icon) and the same
seven nav items in the same order with identical tabler-style icons:
Dashboard · Options Chain · Vol Surface · Strategy P/L · Positions ·
Tracker · Settings. Only the active item differs per page.

Tracker is for symbol price/IV history, not positions. The "Save to
Tracker" button now adds the symbol to a watchlist (localStorage); the
Tracker page shows the watchlist as clickable chips.
New "Enter Position" button on the Strategy page posts the active legs
to /api/orders, then opens the new Positions page.
New Positions page (positions.html): lists entered positions with live
mid value, round-trip commission, gross & net P/L (Net = Gross − round-
trip commission), per-symbol filter, summary totals, close/reopen and
remove actions.
New Settings page (settings.html) configures the commission used on
Positions. Defaults to Interactive Brokers Fixed / IBKR Lite: $0.65
per contract, $1.00 minimum per order
(https://www.interactivebrokers.com/en/pricing/commissions-options.php).
Per-leg vs per-order toggle for complex orders.
Sidebar nav now: Dashboard · Options Chain · Vol Surface · Strategy P/L
· Positions · Tracker · Settings.
