About-tab element refs were cached at script load time but the elements
live inside a <template> that hasn't been cloned yet, so all refs were
null. Convert to lazy resolution via _resolveAboutEls() called on first
about-tab render. Also extract _wireSubTabBar() so sub-tab click
listeners are attached after template cloning (the about Client sub-tab
was unreachable). Decoder status elements use the same lazy pattern.

Move template cloning into navigateToTab() so deferred <template>
content is materialized before any tab-specific initialization runs.
Previously the document-level template cloner fired after navigateToTab
due to event propagation order, causing initAprsMap() and
scheduleStatsRender() to target elements that did not yet exist. Also
defer statistics control wiring until the first render so event
listeners are attached after the template is cloned.

The #sat-status element was stuck on "Waiting for satellite pass" because:
1. The client audio handler (audio_client.rs) did not include AUDIO_MSG_LRPT_IMAGE
in its message type match, so LRPT image messages from the server were silently
dropped and never reached the frontend.
2. No progress was reported during active LRPT decoding — the only status update
happened when a complete image was finalized, which could take the entire pass.
3. The sat-status text was never updated when the decoder was enabled/disabled,
leaving it permanently at the HTML default text.
Changes:
- Add DecodedMessage::LrptProgress variant for live MCU progress reporting
- Send LRPT progress updates from the decoder task when new MCUs are decoded
- Add AUDIO_MSG_LRPT_IMAGE and AUDIO_MSG_LRPT_PROGRESS to client audio handler
- Update sat-status text when decoder state changes (enabled/disabled)
- Handle lrpt_progress messages in the frontend to show "Receiving — N MCU rows"

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().

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.

as constant GET /bookmarks traffic on each spectrum render cycle.
