A stepped ("up-to") default card prices the whole stay as one total, so the V2
engine short-circuits to steppedFee and NEVER consults windowed cards — any
time/seasonal tiers would silently never fire. Found live: an active tariff had a
stepped base plus weekday-night + weekend tiers, and every 3h stay priced 600 ALL
regardless of hour/day because the tiers were dead.
- validateTariffV2 now rejects a stepped defaultCard combined with windowedCards,
with an actionable message (switch the base to ladder/flat, or remove the tiers).
- Composer shows an inline red warning the moment base mode is stepped and tiers
exist; publishing is blocked server-side regardless.
- ApiError now carries the server's problems[], so the publish error surfaces the
SPECIFIC reason instead of a generic "invalid tariff structure".
- 2 new validation tests (55 pass).

Owners often state rates as a total-by-duration matrix (0-1h=200, 0-3h=500,
0-6h=800, 0-9h=900, 0-12h=1000) that the marginal hourly ladder can't express
(the ladder sums per-increment rates; this is cumulative totals at thresholds).
Add STEPPED as a third pricing mode alongside the ladder and flat.
- @parking/shared: TariffStep {uptoMin, totalMinor} + a `steps[]` field on V1
structures and V2 cards (mutually exclusive with blocks/flatMinor). steppedFee():
smallest tier with uptoMin >= duration wins (INCLUSIVE boundary), the top tier
repeats as a per-day cap; wired into computeFeeV1 + computeFeeV2 (V2 default card
only — a whole-stay total can't be sliced per-increment by a windowed card).
Validation: ascending uptoMin, non-negative totals, no daily-cap-with-steps,
steps-only-on-default. priceSession/quote/booth/Lab price it via the shared core.
- Composer UI: a "By duration (up-to)" mode with an up-to/total table (base card
only). i18n modeStepped/steppedHint/stepUpTo/stepTotal/addStep (sq+en).
- 8 new unit tests incl. the exact owner matrix, multi-day repeat, overstay, and
validation (53 pass). Verified end-to-end via the UI: authored + published the
matrix, Tariff Lab prices it exactly (3h->500, 6h->800, 12h->1000, 2d->2000).

The TRM tokens were good but every screen hand-rolled inputs and buttons as
bare outlines on near-black panels, so fields, cards and buttons were
visually indistinguishable. Add a component layer (.input/.select/.textarea
as recessed slots, .btn family with a FILLED primary, .card scaffolding) and
adopt it across the booth/shift/login/tariff/site screens — several of which
were still light-theme inline styles dropped on a dark background.

Bring the legacy ParkSQL2017 pricing BREADTH onto our engine while keeping
integer-minor-unit money + immutable signed versions (rejecting legacy's
float money / mutable rows). TariffStructure becomes a discriminated union:
V1 = the original bare ladder (UNCHANGED, verbatim algorithm, golden-
regression-tested against the live version); V2 = {version:2, tz, shared
knobs, defaultCard, windowedCards[]} where each card is flat OR a block
ladder and may be scoped by wall-clock hour window / day-of-week / date
range / vehicle category.
computeFeeV2 prices by stepping one increment at a time, advancing the
ladder by ELAPSED minutes (continuous) while selecting the active card by
WALL-CLOCK time in the version's FROZEN tz. Decisions: tz is a per-site
setting (site_config.timezone, default Europe/Tirane) stamped server-side
into each version on publish — never the host clock (reproducibility);
default-card cap governs a mixed day; precedence = specificity
(date>dow>hour) -> priority -> name (total, order-independent), validation
rejects ambiguous ties; category = a card FIELD, frozen in the signed
vehicle_entry payload (site_config.default_vehicle_category default), read
at both pricing call-sites.
Composer: default card front-and-centre (flat/ladder toggle), tiers under
an "Advanced" disclosure; emits BARE V1 when no tiers (back-compat). DB:
migrations 0005 (timezone) + 0006 (default_vehicle_category). Stood up
vitest in @parking/shared (was zero tests on the ledger-feeding fee fn);
36 tests incl. golden V1 regression, happy-hour/overnight/dow/flat/category/
cap edges, precedence shuffle-invariance, Europe/Tirane DST determinism,
validation matrix — all green. No event-chain change.

The stepped-block engine already does "first N hrs x X, next N hrs x Y, ...,
24h cap" (ordered blocks, per-block rate, rolling-24h cap). No new axis; this
completes the model and removes its footgun.
- validateTariffStructure (shared) now REQUIRES the last block to be open-ended
(uptoMin: null). A bounded final block silently inherited its own rate past
its bound (a hidden, never-stated price — e.g. the live ALL tariff billed
hour 4+ at the 3rd-hour rate). rateAt() still prices legacy bounded-tail
versions; validation is publish-only, so published immutable versions are
unaffected (no migration).
- TariffComposer edits bands as a DURATION in hours ("first 2 hours, then next
3 hours"), accumulated into the engine's cumulative uptoMin (minutes) on
submit. The last row is a pinned, non-removable "thereafter (open-ended)"
band, so a published card always satisfies the open-ended-last rule.
blocksToForm round-trips stored minutes back to band hours (legacy loads).
- i18n: replaced upToMin/egExample with bandDuration/hoursUnit/egHours (sq+en,
catalog parity green).
Verified: validator rejects bounded-last / accepts open-ended; computeFee
correct at 1/2/3/5/6/24h for a 0-2h@200,2-5h@100,5h+@50 + 1000 cap card. Full
build green. Wiki (tariff.md, log.md) updated.

Add react-i18next with two key-parity-checked catalogs (sq default/fallback, en).
Active language driven by the logged-in user's stored preference (applied after
/me resolves); SQ/EN toggle in the header persists via PUT /api/auth/language.
Translate the booth (screen, pay/exit modal, active sessions, snapshots, status),
Login, ShiftControl, SiteSettings, PermitManager, TariffComposer.
SetupWizard deferred (its content is server-provided; needs backend catalog i18n).
validateTariffStructure (shared): non-negative ints, ascending block bounds,
only the last block open-ended — a malformed card can't be published.
Routes: GET /api/tariff (active + history, any signed-in role), POST
/api/tariff/versions (publish an immutable, effective-dated version; admin
only). The single site tariff row is created lazily. Editing = publish a new
version; past sessions keep their pricing.
Web: TariffComposer in the admin shell — edit currency, grace windows,
increment, daily cap, lost-ticket fee, and add/remove rate blocks (major-unit
input -> minor on submit); shows active version + history.
Verified via inject: empty -> active null; invalid blocks -> 400 with problem;
valid -> 201; readonly publish -> 403; after publishing, the pay station quote
returns 404 (no session) instead of 409 (no tariff) -- it now prices against the
active card.
