JS: fix stereo AudioData channel copy — frame.copyTo with planeIndex:0
only fills the left plane; reading it as interleaved data caused every
other sample to be zero, making WFM stereo play at half speed. Now
calls copyTo per channel with the correct planeIndex.
Rust WFM: replace integer output_decim/output_counter in WfmStereoDecoder
with a fractional phase accumulator (output_phase_inc = audio_rate /
composite_rate). Integer division caused the effective output rate to
drift from audio_sample_rate when the SDR rate is not an exact multiple
(e.g. 2 MHz SDR → 250 kHz composite → ~50 kHz output instead of 48 kHz,
making audio play 4% slow).
Rust non-WFM: add resample_phase/resample_phase_inc to ChannelDsp and
use a fractional-phase resampler in process_block for non-WFM paths,
ensuring exactly audio_sample_rate samples/sec regardless of SDR rate.

Fix updateJogStepSupport to snap jogUnit (not jogStep) to nearest
supported unit, then recompute jogStep = jogUnit * jogMult so the
multiplier is preserved across rig connect/reconnect.
Rename "Mult" label to "Unit Multiplier" for clarity.

Fix waterfall overview freezing at steady state by tracking a monotonic
push counter instead of row array length — the array size stays constant
once the waterfall is full, so the previous row-count comparison never
triggered the incremental draw path.
Fix WFM RDS not decoding when switching to WFM from a narrowband mode:
set_mode now resets audio_bandwidth_hz to the mode-appropriate default
(180 kHz for WFM) before rebuilding the FIR, preventing the 57 kHz RDS
subcarrier from being filtered out.
Add 1×/10×/100× multiplier button group next to the jog unit selector.
jogUnit × jogMult gives the effective jog step; both are persisted to
localStorage independently.

Lower SPECTRUM_POLL_INTERVAL and SSE tick from 100 ms to 200 ms to halve
the number of spectrum frames pushed to the browser.
Introduce an OffscreenCanvas cache for the overview waterfall: at steady
state only the new row is painted and the existing image is scrolled up,
reducing per-frame work from O(rows × cols) to O(cols).

When a WFM/SDR spectrum stream carries RDS data, show the Program
Service name (8-char station name) centered on the visible waveform
area in DSEG14 monospace — the same font as the frequency display.
- Add #rds-ps-overlay div inside .overview-strip (pointer-events: none,
z-index: 2, absolutely positioned at the center of the visible canvas)
- updateRdsPsOverlay(rds) shows/hides and updates text on every spectrum
frame; trims trailing spaces common in RDS PS strings
- Overlay cleared on spectrum disconnect / null frame
- text-shadow uses CSS color-mix against --bg for legibility across all
style/theme combinations

Same root cause as the overviewDrawPending TDZ: setStyle() references
lastSpectrumData at module init time but it was declared far below.

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)

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.
