Subject: [PATCH] Rename the Scenes panel to Authoring and lay it out in steps

The panel reads AUTHORING and groups its controls under SCENE, SHOTS,
PREVIEW and SAVE & SHARE headings, with the EDIT DETAILS / SHARE SCENE
row moved beside EXPORT / IMPORT. Text is larger with more contrast,
shots are numbered, every action has a tooltip and the status line is a
live region. Outside playback, buttons that would do nothing are
disabled. New labels are translated in every shipped language; PLAY
uses its own catalog context apart from the radio's PLAY.

Its compact buttons use the same 176 px width as the left accordion and one consistent 50 px height, share the left stack's 52 px edge inset and measured top baseline across HUD variants, then constrain themselves against visible HUD/chrome rectangles and the remaining vertical corridor. `DISPLAY` is no longer draggable and legacy saved coordinates are ignored.
 - The right rail is labeled **DISPLAY** (formerly "MOVE") and groups, in order, HUD, DETECT, Bloom, Sharpen, 3D, Clean-UI (HUD + DETECT promoted to the top).

It starts expanded on first run and respects the user's later `v6` collapse choice. Collapses/expands with directional chevrons (`◀` collapsed, `▶` expanded).
 - Display and Context use matching 330 px expanded widths and matching compact tab dimensions. The parameter panel is part of Display's expanded content. DISPLAY may remain open beside one contextual panel; CCTV and Context are mutually exclusive. In Tactical HUD, expanding CCTV or Context hides the other contextual launcher while DISPLAY remains independently available. The most recently opened right-rail panel owns the constrained lane even when it appears later in DOM order; passive restoration and automatic disclosure do not replace that explicit owner. Minimal and other HUD layouts retain the collapsed launchers; when their active panel exceeds the measured corridor, the rail reserves sibling heights and gaps and scrolls the active panel internally.

-- **Aircraft cockpit view:** selecting a commercial or military aircraft reveals a `COCKPIT` action (`C`). Cockpit mode temporarily releases Cesium's orbit-follow transform and drives a first-person camera from the tracked aircraft's existing smoothed display position and course. Its concave helmet-visor HUD shows callsign, UTC time, coordinates, curved roll/pitch guides, and a seven-division heading tape. Ambient commercial and military AIR contacts use a Cockpit near/far band selected by the shared Display 3D mode: Proximity admits at 150 km and retains to 185 km; All admits at 400 km and retains to 450 km. The shared 3D toggle now applies in Cockpit: Off keeps in-range contacts as rotating 2D aircraft silhouettes, while On lets a ready admitted glTF take over without a drawing gap. The Cockpit model cap remains 60 and can only lower the map budget; in-range contacts that are capped or still loading remain 2D silhouettes instead of degrading to out-of-range dots. Contacts outside the selected band use small rotation-free cyan-white pips for civilian aircraft and amber pips for military. The pilot's own airframe is not drawn in first person, and exiting clears the Cockpit band and restores normal map silhouettes/models. The normal left accordion remains available for Layers and Scenes and keeps the same 26vh HUD-aligned anchor used in map mode, independent of whether the bottom-left Contact card is expanded or collapsed; the right-rail CCTV and Context chooser are hidden to avoid duplicating or overlapping the cockpit presentation. When the intelligence HUD is enabled, its classification, scene summary, collection/orbit metadata, coordinates, and imaging-status text remain visible as reduced peripheral cockpit telemetry; the optical center and flight instruments stay clear, and turning the HUD off still hides it. Ground speed, exact heading, and rendered altitude form one compact lower-center instrument cluster, keeping the horizon and peripheral view open. A second live altitude tape hugs the inside-right visor rim: its rail and nine moving ticks are derived from the same responsive keyhole radius, remain 20 px inside the circular edge even on wide displays, fade deeply at both vertical ends, and move continuously behind a fixed current-altitude pointer; its interval tightens automatically near the surface and it is suppressed on narrow screens. Cockpit mode also has a weather-backed transparent volumetric-cloud pass derived from the supplied FBM/domain-warped R&D shader. It renders at no more than 520×320, uses 24 ray steps/three FBM octaves at 12 FPS, is clipped to the visor, fails clear when Open-Meteo is unavailable, and stops its animation completely on cockpit exit. It does not restore the prior CPU weather canvases, precipitation, scene fog, or any map-mode effect. When Contacts is active for the tracked aircraft, the compact `CONTACT` rail adds the 250 km subject window, four cohort counts, nearest observed/mapped example with relative bearing and distance, freshness, explicit uncertainty, and Previous and Next controls plus its own collapse control. The mirrored right rail is a three-page **cockpit briefing carousel**: source-backed live signals, location-matched regional headlines, and physical-region/current-weather context from bundled Natural Earth polygons and Open-Meteo. It is manual-first: Previous, Next, and direct page controls are always available, and the visible `CYCLE OFF` / `CYCLE ON` control starts or stops the nine-second page cycle. The cycle pauses on hover or keyboard focus and stops while collapsed, hidden, or outside cockpit mode; live signal data continues refreshing either way. Empty news matches and unavailable news use compact text states rather than reserving an empty media frame; partial local data remains explicit. Article links open their original publisher, and no headline is treated as verified risk intelligence. On desktop both cockpit rails use the same width and share a bottom-aligned safe baseline in opposite corners above the peripheral MGRS/GSD/time telemetry, leaving both that text and the lower-center instrument cluster readable. They collapse independently to slim tabs without stopping live data updates. Narrow screens use separated top/bottom fallbacks. Empty-space globe clicks are inert while cockpit owns the camera; `C`, `Escape`, or `EXIT COCKPIT` explicitly exits and restores the same tracked entity and standard follow camera. Unknown feeds remain unknown, selection loss still exits safely without inventing a replacement track, and the cockpit never presents the summary as threat scoring or an all-clear. This is a desktop first-person presentation, not a WebXR session.

+- **Cockpit left-panel clearance:** the Cockpit Contact card and peripheral HUD participate in the adaptive left accordion's live obstacle measurements, including live viewport-height changes. Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
 - **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls replace reliance on the `C` shortcut. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, `NOIR`, and `SNOW`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.
