Shipped 2026-05-18. NIX-OS-91 -- after the configured idle threshold the Customer Display Screen dims to a near-black sleep overlay (Moon icon centered, 15% opacity). Wakes instantly when the cashier rings a new item. Off by default; admin picks the threshold per-tenant from Settings -- Customer Display -- Screensaver: Off / 5 min / 10 min / 30 min.
display_screensaver_seconds=300 to the DB; selecting Off + Save persists NULL.
Migration 20260518000000_cafe_display_screensaver: adds
cafe.tenant_config.display_screensaver_seconds (integer NULL) +
CHECK constraint allowing NULL OR IN (300, 600, 1800). Idempotent (ADD COLUMN
IF NOT EXISTS + DO block for the constraint).
DAO + constants: SCREENSAVER_VALID_SECONDS +
ScreensaverSeconds type in lib/display_branding_constants.ts.
getDisplayBranding reads it; saveDisplayBranding writes it;
validateBranding enforces the enum (rejects 42 with a clean error).
Settings form: new "Screensaver" card on
/cafe/settings/display with Off/5/10/30 min pills. Same visual treatment as
the Slice G slideshow speed pills.
Display client: asleep state +
lastActivityRef + 5-second-tick interval that only spins up when
screensaver is enabled (no CPU cost for tenants who don't opt in). Idle echoes from
the polling fallback don't reset the activity clock -- only cart/paid messages do.
Paid-screen pin (6s) takes precedence over sleep. When idle resumes (paid expired),
the activity clock resets so the timer counts from "just became idle".
lumiere-coffee (Starter) has no cafe.tenant_config row on prod.
First prod run failed 2/5 on lumiere because saveDisplayBranding does an
UPDATE WHERE tenant_id=... that silently no-ops for tenants without a row.
This is a pre-existing gap, not introduced by Slice M -- it predates
Slice G's slideshow feature too. Switched the Slice M prod test to get-coffee
(Pro) which has a tenant_config row; all 5 checks passed.
Follow-up: saveDisplayBranding should UPSERT not UPDATE so
Starter tenants without an existing config row can configure display branding (including
screensaver) from a fresh state. Tracked as a separate small ticket -- not blocking
Slice M because Narong primarily tests on get-coffee Pro.

Verified on prod via Playwright probe that the ShopSelector is already
tier-gated on Starter: LockedForTier wraps it with
aria-label="Multi-shop is available on Pro", a lock badge SVG, and
opacity-50 dimming. Narong's NIX-OS-93 ticket appears to predate Slice F
(which integrated this gating). No code change for NIX-OS-93 -- already shipped.
"Reports similar to Loyverse" is too underspecified -- waiting for Narong's spec (overlaps with v0.2 H5.9 Reports Summary which is also parked pending spec).
