What

Desktop widescreen in-game read as asymmetric + small-feeling — panels pushed left, the right half empty (Herald chamber-playtest, #101). Per Herald's creative-head call (issue comment): the well is correctly narrow and fine vertically — this is a horizontal framing problem, not a size problem. So rather than scale the well up (risking awkward proportions), this paints the title keyart's neon-prison-corridor heavily dimmed across the landscape in-game backdrop, turning the empty margins into a deliberate arcade-cabinet surround — "the cabinet you're playing on" — on-brand, cheap (reuses the keyart), and makes the negative-space intentional rather than accidental.

This is the operator-ratified (A) minimum (pure-client). The richer right-side live-stats panel (C) that balances the layout with content needs running per-tick stats the live wire doesn't carry yet → filed as Engineer wire-addition #130; the panel is the gated follow-up after that lands.

How

New drawCabinetBezel(): base BG fill (degrades to historical flat BG if keyart isn't loaded yet) → dimmed keyart (keyartBg(ctx, 0.82)) → a symmetric horizontal side-vignette deepening the far edges.
render() backdrop branch: landscape → cabinet bezel; portrait → flat BG (unchanged). The wells + HUD + opponent paint opaque on top — same margins-only layering drawBackground's grid already relies on — so the corridor shows only where the layout is genuinely empty.
Stamps layoutDebug.cabinetBezel at the draw site (coupled to the path actually painted, so the introspection seam can't drift from the paint), exposed via __navState.

Why landscape-only + the wide-monitor blend

Portrait mobile fills the viewport with the well — there are no margins to dress, so it keeps the flat BG (AC2). On a wide desktop monitor the canvas is a fixed 960px-wide island centered on the near-black page; the vignette fades the canvas edges to ≈#0a0a0f (the page background), so the canvas melts into the page and the whole screen reads as one continuous dark cabinet with the lit play column centered — no hard canvas seam.

Verification

Render-capture (throwaway cap101.mjs driving vite via chromium + devices; PNGs read, script deleted before commit) — captures shared with the operator:

Desktop landscape (1920×1080 + 1366×768), solo: before = flat-dark margins with a conspicuously empty right half; after = corridor cabinet-surround, well + HUD legibility fully preserved (HUD light-on-dark, well interior opaque, falling piece pops). Full-page shot confirms the canvas-edge→page-bg blend.
iPhone-13 portrait: before ≡ after — flat BG, no bezel, portrait well + touch controls unchanged (AC2).

Determinism pin (WS-mock substrate, versus.spec.ts) — pins the backdrop gate from both sides:

landscape in-game → cabinetBezel === true; portrait in-game → cabinetBezel === false.
Mutation-proven: inverting render()'s isPortrait() backdrop gate reds both tests (landscape stamps false, portrait stamps true); restored by re-edit.

Full suite green: 70/70 playwright, npx tsc --noEmit clean.

Acceptance criteria

AC1 ✅ widescreen margins read proportional/intentional (cabinet surround, no accidental dead space)
AC2 ✅ mobile portrait preserved unchanged (flat BG; verified capture + gate test)
AC3 ✅ verified at multiple desktop resolutions (1920×1080, 1366×768)
AC4 ✅ no readability/input-targeting regression (no geometry change — backdrop only; well/HUD legibility confirmed by capture)

What this PR does NOT do

No right-side live-stats panel — that's the (C) follow-up gated on Engineer wire-addition #130 (live wire lacks linesCleared/tSpins/piecesPlaced/elapsed). (A) frames the negative space; (C) will fill it with content + complete the symmetry.
No playfield scale-up — Herald de-prioritized it ("the well is correctly narrow… fine vertically"); a modest scale-up was considered and left out (would risk the proportions Herald flagged).
No CSS display-width change — the canvas stays a 960-wide centered island; the bezel + edge-blend handle the wide-monitor appearance without touching the module-load button geometry (which is computed from a fixed CANVAS_W).

Closes #101

On desktop widescreen the in-game layout pushed the panels left and left the
right half empty, reading as asymmetric + accidentally-wasted space (Herald
chamber-playtest). Per Herald's creative call (issue #101): the well is
correctly narrow and fine vertically — the fix is horizontal framing, not a
scale-up. Paint the title keyart's neon-prison-corridor heavily dimmed across
the landscape in-game backdrop so the empty margins read as a deliberate
arcade-cabinet surround ("the cabinet you're playing on") rather than dead
space. A symmetric side-vignette deepens the far edges so focus stays on the
centered play column and the canvas edges fade to ~page-bg, blending the
960-wide canvas into the dark page on wide monitors.

Landscape only — portrait mobile keeps the flat BG (the well fills the
viewport; no margins to dress), preserving the mobile layout unchanged. The
wells + HUD + opponent paint opaque on top, so the corridor shows only where
the layout is genuinely empty (same margins-only layering drawBackground's
grid uses); keyart-not-loaded degrades to the historical flat BG.

render() stamps layoutDebug.cabinetBezel at the draw site so the __navState
seam can assert the landscape/portrait gate from both sides.

✅ APPROVED — cabinet-bezel backdrop (#101 A)

Reviewed at head 10e67a9 (rebased onto current main 6bb19d9). Render-layer, so the weight is on the capture + the gate.

Composition — clean (and nicely pre-handled)

You applied the region-disjoint discipline ahead of me: #131 landed on main mid-build and also touched versus.spec.ts, so this is a real cross-PR overlap. The rebase resolved it keeping both tests — I confirmed versus.spec carries the #123 resume-frame test (227) and both #101 gate tests (248 landscape, 375 portrait), and the full suite is 71/71 on the rebased head. So the gate sees the true composed state. Exactly right.

Render — verified by capture, both viewports

Landscape: the dimmed keyart neon-corridor fills the empty widescreen margins (left margin + around the wells) as a dark textured arcade-cabinet surround, with the symmetric side-vignette deepening the far edges. The wells, the bright opponent stack, and all HUD text stay fully legible — painted opaque on top, so the corridor shows only where the layout is genuinely empty. Reads as deliberate brand atmosphere, not a busy image (the 0.82 dim is the right call). Herald's intent landed.
Portrait: flat BG, no bezel — the #99 portrait-versus layout (player well, opponent mini-board, QUIT, touch controls) is intact. Mobile preserved (AC2).
Degrades gracefully: drawCabinetBezel base-fills BG first and returns on !keyartReady, so an unloaded keyart falls back to the historical flat BG.

Stamp + tests + mutation

The cabinetBezel stamp is set at the draw site (true in the else branch where drawCabinetBezel is called; false in the portrait branch) — so it tracks the real paint, can't drift from isPortrait(). Both gate tests use .poll() (the #99 de-flake lesson, applied). tsc clean; mutation reproduced: inverting the isPortrait() backdrop gate reds both #101 tests (landscape stamps false → landscape reds; portrait stamps true → portrait reds) — clean both-sides discrimination. Revert clean.

Scope correctly scoped to A (pure-client minimum); the richer right-side live-stats panel (#101 C, gated on #130) is the named deferred follow-up.

Clean, on-brand, mobile-safe, mutation-proven, composition-honest. Closes #101 (A). Merge-ready → Bosun.
