Same root cause as the overviewDrawPending TDZ: setStyle() references
lastSpectrumData at module init time but it was declared far below.
Hoist let lastSpectrumData = null to the top variable block and remove
the now-duplicate declaration.

setStyle() was called at module init time (to restore the saved style
from localStorage) before the let overviewDrawPending declaration, which
caused a ReferenceError: Cannot access 'overviewDrawPending' before
initialization.
Fix: hoist let overviewDrawPending = false to the top of the variable
declarations block, before any top-level code that may call
scheduleOverviewDraw(). Remove the now-duplicate declaration from its
original location.

Add a style picker dropdown to the tab bar (right of rig picker) with
four styles — Original, Nord, Monokai, Contrast — each with full
light/dark variants.
CSS: define data-style attribute overrides for all CSS custom properties
(bg, card-bg, borders, text, accents, jog, audio level, filter, spectrum
background) for each of the three new styles × two themes (6 new blocks).
JS: introduce CANVAS_PALETTE lookup table covering spectrum/waveform/
waterfall colors for all style×theme combinations. Add currentStyle(),
canvasPalette(), setStyle() helpers. Persist selection to localStorage.
Replace all isLight ternaries in drawing code with palette lookups:
- drawOverviewWaterfall, drawOverviewSignalHistory, waterfallColor
signatures changed from isLight flag to pal object
- drawSpectrum uses canvasPalette() for grid lines, labels, fill, line
- spectrumBgColor() now delegates to canvasPalette().bg
Theme toggle also triggers a spectrum redraw so canvas colors update
immediately when switching light/dark.
Also fix light-theme spectrum rendering broken since canvas drawing used
hardcoded dark-only colors (white grid lines invisible on light bg).

- Add viewport meta tag so mobile browsers use device width instead of
the default 980px desktop viewport
- Add 520px breakpoint: remove controls-tray forced min-width (was
52–58rem, causing horizontal scroll on phones), stack controls-row
into a single column with jog wheel first (order: -1)
- Scale frequency DSEG14 display with clamp() on narrow screens
- Make volume sliders responsive width with larger 20px thumb
- Raise spectrum Set/Auto button and input heights to 2.2rem (overrides
the min-height: 0 that blocked the existing 760px touch-size rule)
- Add overflow-x: auto + flex-shrink: 0 to sub-tab-bar so all six
plugin tabs are reachable on small screens without clipping
- Swap spectrum hint text based on input device: mouse/keyboard hint
hidden on touch devices, touch-specific hint shown instead
- Offset S0/S9/S9+ signal history labels 6px below their grid lines

Replace the BW slider + FIR taps filter panel with a visual bandwidth
bookmark drawn directly on the spectrum canvas:
- Semi-transparent amber gradient strip spanning dialFreq ± BW/2
- Rounded-top bookmark tab at the top of the strip showing the current BW
- Draggable left/right edge handles (cursor: ew-resize) that adjust bandwidth
live and send set_bandwidth on mouse-up; range clamped per-mode defaults
- Y-axis now labeled with dB values (floor to ceiling) drawn on canvas
- Configurable floor level via number input below spectrum (default -100 dB)
- Auto button fits floor/range to current noise floor and peak level
- Remove FIR taps selector (internal DSP implementation detail)

Add MODE_BW_DEFAULTS table mapping each mode to [default, min, max, step]
in Hz. When mode changes (via picker or SSE), applyBwDefaultForMode
updates the filter bandwidth slider range and sends set_bandwidth to the
server, so the DSP filter is rebuilt automatically for the new mode.

Spectrum panel is now placed above the freq/mode/jog row, spanning the
full card width. Key improvements:
- Scroll wheel zooms in/out at the cursor position (up to 64x); double-
click resets to full bandwidth view.
- Mouse drag pans the visible window; click-to-tune is suppressed when a
drag has occurred.
- Touch pinch-to-zoom and single-finger drag-to-pan supported.
- Hover tooltip shows the frequency under the cursor, formatted to the
currently selected unit (MHz/kHz/Hz, matching the jog-step selection).
- Frequency axis labels update to reflect the zoomed visible range.
- Canvas height increased to 160 px; axis bar styled with card bg.
- A small hint line below the panel explains the controls.

Poll GetSpectrum every 200 ms in remote_client via a dedicated timer that
bypasses the main state-watch channel (no SSE noise). The resulting
SpectrumData is stored in FrontendRuntimeContext::spectrum and served by
a new GET /spectrum endpoint (JSON or 204 when unavailable).
HTTP frontend shows a spectrum panel (canvas + frequency axis) only when
the rig reports filter_controls=true (i.e. SoapySDR). The canvas renders:
- dark background with dBFS grid lines
- green FFT spectrum line with semi-transparent fill
- red dashed vertical marker at the currently tuned frequency
- frequency axis labels (MHz/kHz) below the canvas
Clicking the canvas tunes the rig to the clicked frequency.

Hide the header rig picker when showing the authentication gate,
since no rigs are accessible until the user authenticates.
Show the picker again when auth gate is hidden (after login).
This improves UX by not showing an empty picker to unauthenticated users.

Use header rig selector as the single point for rig switching. Remove
redundant about page rig selector controls and associated JavaScript
event listeners.
