The spectrum floor/gamma IIFE (line 11507) was missing its closing
`})();`, causing all bandplan strip variables and functions to be
trapped inside the IIFE scope. This made `bandplanRegion`,
`updateBandplanStrip`, and `_bandplanServerDefaultApplied` invisible
to the rest of the file, throwing ReferenceErrors that crashed
`render()` before the frequency display update could run — leaving
the frequency input stuck at its initial "--" placeholder.

The "Decodes by type" statistics panel only showed AIS because
statsRecordDecode was only called from dispatchDecodeMessage, which
was bypassed by two code paths:
1. dispatchDecodeBatch: uniform-type batches dispatched to specialized
batch handlers (onServerFt8Batch, etc.) returned early without
recording stats.
2. restoreDecodeHistoryGroup: history messages restored on page load
were never recorded in the statistics log.
Fix both paths by recording stats up-front in dispatchDecodeBatch
before dispatching to batch handlers, and in restoreDecodeHistoryGroup
before restoring to plugin views. Add a skipStats parameter to
dispatchDecodeMessage to prevent double-counting when the fallback
per-message loop runs inside dispatchDecodeBatch. Also accept an
optional timestamp in statsRecordDecode so history entries use their
original ts_ms rather than Date.now().

Move bandplan segment rendering from DOM elements to WebGL, drawing
coloured rectangles at the bottom of the spectrum canvas (above the
waterfall). All segments are batched into a single drawTriangles() call
for efficiency. The DOM strip is reparented into .spectrum-wrap and
restyled as a transparent text-label overlay (bp-webgl class). Non-SDR
rigs without a spectrum canvas retain the original DOM-coloured fallback.

Add the three missing VDES decoder components per ITU-R M.2092-1:
- turbo.rs: Turbo FEC decoder with dual 8-state RSC constituent
encoders, BCJR/MAP iterative decoding (8 iterations), QPP
interleaver, and rate-1/2 depuncturing
- crc.rs: CRC-16-CCITT validation (poly 0x1021, init 0xFFFF) for
decoded link-layer frames
- link_layer.rs: Structured parsing of M.2092-1 link-layer frames
(Messages 0-6) including station addressing, ASM identification,
geographic bounding boxes, and ACK/NACK reporting
The main decode pipeline now attempts turbo decoding first with CRC
validation, falls back to Viterbi when turbo fails, and reports
crc_ok=true when either path validates. 27 tests covering all new
modules.

Meteor-M2 3/4) that auto-fills name and NORAD ID
- Bookmark selector for each satellite (sets freq, mode, decoders)

The render() function runs on every SSE event (5-20×/sec) and was
unconditionally writing to decoder toggle buttons and About-tab
decoder status elements — 8 getElementById calls + 32 DOM property
writes per frame — even when values hadn't changed. This caused
unnecessary style recalculation overhead on every SSE frame,
contributing to spectrum stuttering.
Changes:
- Cache all 7 decoder toggle button elements at module init instead
of calling getElementById on every render() call
- Track last-written enabled state per button; skip DOM writes when
the value is unchanged (steady-state cost: 0 DOM writes per frame)
- Same pattern for 8 About-tab decoder status elements
- Gate updateSatLiveState className/textContent writes on value change
Net effect: eliminates ~50 unnecessary DOM operations per SSE frame
during normal operation (decoders rarely toggle).

Six hot-path optimizations that reduce per-frame CPU cost:
1. Waterfall color LUT: Pre-compute a 256-entry RGBA lookup table
(bins are i8 = 256 possible values) instead of calling
waterfallColorRgba() per-pixel with HSL→RGB math + Math.pow().
Eliminates ~2000+ HSL conversions per frame across both waterfalls.
2. Noise floor O(N)→O(N log N): Replace .slice().sort() with an
in-place quickselect algorithm for 15th-percentile estimation.
For 1024 bins this is ~10× faster.
3. Reuse spectrum bin buffers: SSE handler and buildSpectrumRenderData
now reuse pre-allocated arrays instead of creating new Array(N)
and .map() allocations every frame. Reduces GC pressure.
4. Cache canvas dimensions: drawSpectrum and drawSpectrumWaterfall
read cached CSS dimensions instead of querying clientWidth/
clientHeight every frame (which forces layout recalculation).
Dimensions refreshed on resize and layout changes.
5. Cache DOM references: getElementById calls for zoom indicator and
minimap elements moved to module-level constants instead of
querying the DOM on every drawSpectrum call.
6. Efficient array trimming: Peak hold pruning uses in-place splice
from front instead of .filter() (which allocates a new array).
Waterfall row trimming uses splice instead of repeated .shift().

Three issues in the satellite predictions view caused page-wide
rendering performance degradation:
1. Unbounded DOM nodes: All satellite passes (200+ satellites × multiple
passes = 500-1000 rows with 5 spans each) were rendered at once,
creating thousands of DOM nodes that slowed style recalculation and
layout across the entire page. Now caps at 50 visible rows with a
"Show more" button.
2. No DOM cleanup on view switch: Prediction rows persisted in the DOM
when navigating away from the predictions view or the SAT tab,
bloating the page DOM indefinitely. Now clears prediction DOM when
leaving the predictions view or switching decoder tabs.
3. Countdown timer never paused: The 1-second setInterval with
querySelectorAll kept running even when the predictions view was
hidden, wasting CPU on invisible DOM queries. Now only runs when
predictions view is active, caches element references instead of
querying the DOM each tick, and auto-pauses when the view is hidden.
Also caches prediction DOM element references at module init instead
of calling getElementById on every render invocation.

applyRigList() was called on every SSE state update (since `remotes`
is always present in the payload), and it unconditionally called
bmFetch() which fires 2x GET /bookmarks (list + overlay). At the
default poll rate this generated ~20 bookmark fetches/second — visible
as constant GET /bookmarks traffic on each spectrum render cycle.
Now track the previous rig list + active rig as a key and only
re-fetch bookmarks (and re-init scheduler/background-decode) when
the rig list actually changes.

Two issues introduced with wxsat/satellite support caused indirect
performance degradation on the spectrum rendering path:
1. spawn_tle_refresh_task() was called inside spawn_rig_audio_stack(),
which runs per-rig. With N rigs this spawned N redundant TLE refresh
tasks, each making 3 concurrent HTTP requests to CelesTrak and
competing for write locks on the global TLE store. Moved to a single
global call after the per-rig loop.
2. compute_upcoming_passes() (SGP4 propagation for 200+ satellites over
24h = ~300K propagation steps) ran on every GetSatPasses request with
no caching. Multiple client connections could trigger concurrent
CPU-heavy computations, causing cache pollution and tokio runtime
contention that indirectly slowed spectrum frame processing. Added a
60-second server-side cache shared across all client connections.
