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

When in dark mode the button has a light appearance; when in light mode
it has a dark appearance. This makes the button a preview of what
clicking will switch to, rather than mirroring the current theme.

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

The SDR audio bridge was forwarding PCM to server-side decoders but
never encoding it to Opus for rx_audio_tx, so TCP audio clients
(browser RX button) received nothing. Add Opus encoder initialised
from the rig's audio config and encode each PCM frame alongside the
pcm_tx broadcast.

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.

- Compute hardware center as dial - center_offset_hz (was ignoring offset)
- Pass configured bandwidth_hz to device instead of hardcoded 1.5 MHz
- Add retune_cmd channel so set_freq repoints SDR hardware in real time
- Auto-add default channel with mode-appropriate bandwidth when [[sdr.channels]]
is empty, preventing silent audio with minimal config
- Add ChannelDsp::set_filter to rebuild FIR LPFs at runtime; wire
set_bandwidth and set_fir_taps to call it so UI filter changes take effect
