Wrap the toolbar card and the skew-metric badges (ATM IV / RR25 /
Fly25) in a left column, and place the HV-vs-IV card in a sibling
right column with h-100 d-flex flex-column so it stretches to the
full height of both stacked items — effectively a rowspan=2 layout.
On screens narrower than lg the right column drops below as a
single full-width card.

User wanted the comparison sitting alongside the Lookup / Expiry /
Load Surface controls instead of in the page header. Now it lives
on the right side of the toolbar row (ms-sm-auto), still hidden
until data is loaded.

Adds a compact card in the page header that shows ATM IV alongside
realized vol over 20/30/60-day windows, the IV-minus-HV spread in
vol points, and a RICH/FAIR/CHEAP verdict (driven by IV/HV30 ratio:
>=1.20x = RICH, <=0.80x = CHEAP, otherwise FAIR). Lets you eyeball
whether options are priced rich relative to recent realized vol the
moment the surface loads.
- datafetch.ts: extract annualizedVolWindow helper; new
fetchHistoricalVolWindows() returns hv20/hv30/hv60 from one
~90-day Yahoo historical pull
- options.ts: /api/analytics includes hvWindows in response
- surface.html: top-right hviv-card with per-window rows + footer
showing IV/HV ratio and sample size

New /movers page surfaces Yahoo Finance's predefined screeners
(day_gainers, day_losers, most_actives, most_shorted_stocks)
filtered to common equities with market cap >= $2B, so every
listed name has a deep options chain. Per-row actions jump
straight into Chain / Vol Surface / IV Spike Scanner, or pin
the symbol to the Tracker watchlist.
- datafetch.ts: fetchMovers(category, count) using yf.screener,
post-filtered to quoteType=EQUITY and marketCap >= $2B
- options.ts: GET /api/movers?category=&count=
- movers.html: Tabler page with 4-tab segmented control, sortable
table, summary cards, volume-vs-avg ratio highlighting hot names
- All page sidebars: insert "Movers" link between Vol Surface
and Scanner

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.
