fix: skip vcgencmd throttle probe when binary is absent

The system metrics collector daemon thread ran vcgencmd via subprocess
every 3s even on non-Pi hosts, where it always failed — and leaked
Popen calls into any later test mocking subprocess (intermittent
test_weather_sat_decoder failure in full-suite runs).

 ### Frontend Structure
+- **UI direction (decided 2026-06-12)**: map-heavy modes get dedicated dashboard
+  pages (`/adsb/dashboard`, `/ais/dashboard`, `/satellite/dashboard`); the SPA
+  in `index.html` keeps text/scan modes. APRS and Meshtastic are map-centric
+  and should migrate to dashboards under their own plans — do not grow their
+  SPA footprint.
 - **Templates**: `templates/index.html` (main SPA), `templates/partials/modes/*.html` (sidebar panels), `templates/partials/nav.html` (global nav)
 - **JS Modules**: `static/js/modes/*.js` - IIFE pattern per mode (e.g., `WeatherSat`, `SSTV`, `Meshtastic`)
 - **CSS**: `static/css/modes/*.css` - scoped styles per mode, CSS variables for theming (`--bg-card`, `--accent-cyan`, `--font-mono`)
-- **Mode Integration**: Each mode needs entries in `index.html` at ~12 points: CSS include, welcome card, partial include, visuals container, JS include, `validModes` set, `modeGroups` map, classList toggle, `modeNames`, visuals display toggle, titles, and init call in `switchMode()`
+- **Mode Integration**: Each mode is declared once in `static/js/mode-registry.js`
+  (label, group, elementId, module, init/destroy hooks, visuals flag). The
+  catalog, sidebar toggles, destroy map, visuals list, and init dispatch in
+  `templates/index.html` are all derived from it. A new mode additionally needs:
+  its partial in `templates/partials/modes/`, entries in the CSS/JS lazy-load
+  asset maps in `index.html`, and its include in the partials block.
+  `tests/test_mode_registry.py` enforces registry/asset consistency.

+# Pager & 433 Sensor Display Revamp
+
+**Date:** 2026-05-21
+**Status:** Approved
+
+## Overview
+
+Replace the plain chronological card feed for the Pager and 433 Sensor modes with purpose-built views that better surface the structure of each signal type. Both new views are opt-out (toggle to classic feed available).
+
+---
+
+## Architecture
+
+The two modes use slightly different DOM strategies suited to each layout.
+
+**Pager:** `#pagerDirectoryView` is the left directory panel only. The output panel parent switches to `display: flex` in directory mode, placing the directory panel and `#output` side by side. `#output` becomes the right feed panel — no duplication, no hidden copy.
+
+**Sensor:** `#sensorDashboardView` is a full-replacement grid that sits alongside `#output`. In dashboard mode `#output` is hidden but continues to receive classic `signal-card` insertions so export and filtering remain intact.
+
+```
+[output-panel]  (flex in pager directory mode)
+  [#pagerDirectoryView]    ← left dir panel only; shown in pager directory mode
+  [#sensorDashboardView]   ← full replacement grid; shown in sensor dashboard mode
+  [#output]                ← right feed panel (pager) or hidden (sensor); always updated
+```
+
+`addMessage()` gets a hook to `PagerDirectory.addMessage()` for directory panel updates only (the feed is `#output` itself). `addSensorReading()` gets a hook to `SensorDashboard.addReading()` for station card updates. No other existing logic changes.
+
+### New files
+
+| File | Purpose |
+|------|---------|
+| `static/js/components/pager-directory.js` | PagerDirectory component |
+| `static/js/components/sensor-dashboard.js` | SensorDashboard component |
+| `static/css/components/pager-directory.css` | Directory view styles |
+| `static/css/components/sensor-dashboard.css` | Dashboard view styles |
+
+`templates/index.html` gets:
+- Two new sibling containers (`#pagerDirectoryView`, `#sensorDashboardView`)
+- Toggle buttons in the output panel header (one per mode, shown when that mode is active)
+- Script/link tags for the four new files
+- One-line hook calls inside `addMessage()` and `addSensorReading()`
+
+---
+
+## Pager — Source Directory View
+
+### Layout
+
+Split panel, full height of the output area:
+
+- **Left (200 px fixed):** address directory panel
+- **Right (flex):** full message feed
+
+### Directory panel (left)
+
+- One row per unique pager address seen this session
+- Sorted by message count descending (most active at top)
+- Each row shows:
+  - Protocol badge (`P` = POCSAG, `F` = FLEX), coloured accordingly
+  - Address string
+  - Message count (`×24`)
+  - Relative-width activity bar (count relative to the highest-count address)
+  - Last-seen relative timestamp (`just now`, `2m ago`)
+  - Green dot when a new message arrives from that address (fades after 3 s)
+  - Blue left-border accent on the currently highlighted address
+- Directory state is in-memory for the session only (not persisted)
+
+### Feed panel (right)
+
+- Shows **all messages** at all times (no filtering)
+- When an address is highlighted via the directory:
+  - Feed scrolls to that address's most recent card
+  - All cards from that address get a blue left-border + subtle background tint
+  - Sub-header shows `"<address> highlighted"` with a "clear highlight" link
+- Clicking "clear highlight" (or clicking the same address again) removes all highlighting and returns to the plain feed
+- Cards are otherwise identical to the existing `signal-card` format
+
+### Toggle
+
+- Button group top-right of the output panel header: **Directory** | **Feed**
+- Default: **Directory**
+- Preference saved to `localStorage` key `pagerView` (`'directory'` | `'feed'`)
+- Restored on mode switch
+
+---
+
+## 433 Sensor — Station Dashboard View
+
+### Layout
+
+Responsive CSS grid of station cards (3 columns on typical desktop width, wrapping as needed).
+
+### Station card
+
+One persistent card per unique device, keyed by `model + id`. Cards are created on first reading and updated in place on subsequent readings from the same device.
+
+Each card contains:
+
+- **Header:** device model name (e.g. `Acurite-Tower`), device ID + channel, last-seen relative timestamp (green when < 10 s)
+- **Readings:** the primary numeric values for that device (temperature, humidity, pressure, wind speed, rain, etc.) — label + value + unit, displayed as a small inline grid
+- **Sparkline:** SVG polyline tracking the primary numeric value across the last 30 readings. Colour matches the reading type (amber for temperature, blue for humidity/wind, purple for pressure). A filled circle marks the latest data point.
+- **Footer:** battery status (green `BAT OK` / red `BAT LOW`), SNR value, frequency badge
+
+### State-only devices
+
+Devices that emit only a state (doorbells, PIR sensors, etc.) get a card with a state indicator (coloured dot + label e.g. `MOTION DETECTED`) in place of numeric readings. The sparkline area is replaced with an "event-only device" label. Card still flashes on each event.
+
+### Flash on update
+
+When a new reading arrives for a known device:
+- Card receives a CSS animation class that briefly tints the background (blue for temp sensors, purple for other types) and fades back to normal over ~0.8 s
+- Values update in place; the sparkline dot advances right
+
+### New device appearance
+
+First time a device is seen: card slides in with a subtle green border accent. The border fades to normal after the first update.
+
+### Toggle
+
+- Button group top-right of output panel header: **Dashboard** | **Feed**
+- Default: **Dashboard**
+- Preference saved to `localStorage` key `sensorView` (`'dashboard'` | `'feed'`)
+- Restored on mode switch
+
+---
+
+## Shared behaviour
+
+- Both toggles are shown only when the relevant mode is active
+- Classic `#output` feed always receives cards in the background (export, CSV/JSON, existing filter bar all continue to work)
+- No changes to SSE handling, process management, or backend routes
+- No new backend endpoints required
