Detail category BSR is more granular and relevant per ASIN. Falls back
to topLevelBSR if detailLevelBSR is null for a record.

Math.max(...largeArray) crashes when combinedAdsData has thousands of
records. Replaced with a simple for-loop to find the max year safely.

New BSRUnitsCorrelationChart component added to the Vendor tab showing:
- Per-marketplace tabs (DE, ES, FR, IT, UK) with market accent colors
- Dual-axis combo chart: bars (units sold, right axis) + line (BSR rank, left axis)
- Inverted BSR axis by default (lower rank = top) with toggle to flip
- Pearson r correlation calculated and displayed with strength interpretation
- Wired to existing combinedAdsData (filtered) and filteredBsrData

The badge was rendered outside the stockMap conditional, causing it to
appear independently of the Amazon stock badge. Now it's grouped inside
the block, always appearing immediately next to VendorStockBadge.

The BuyBoxWarningBadge was appearing twice - once next to the SKU and once next to Amazon stock. Now it only appears next to Amazon stock as requested.

Each market line (DE/ES/FR/IT/UK) now renders with its own color across
Top Level BSR, Detail Level BSR, and Average Rating charts, along with
per-market legend entries. Removes hardcoded single-color approach.

Add translateCategory() with a full DE/FR/IT/ES → EN map covering
all top-level and detail categories found in the BSR data.

Replace bar charts with area charts featuring:

Convert Top Level BSR, Detail Level BSR, and Average Rating charts
from LineChart to BarChart for better week-over-week comparison.
Each market now displays as colored bars per week instead of lines.

The badge was only rendered for dim==='asin'|'sku'. When pivoting by
title (the default view) the BuyBox warning was silently absent.

Add support for European day-first date format (e.g. "23/2/26" = 23 Feb 2026)
in the sell-out CSV pipeline so months and years are correctly extracted from
column C of Amazon Sell Out 2023-2025.csv.
- normalizeMonth: detect DD/MM/YY when first part > 12, return "Mon-YY"
- mapRowToRecord: add 'C', 'Date', 'Fecha', 'DATA' to month column aliases
- validateSellOutHeaders: accept date columns as substitute for YEAR + MONTH

- Agregar tarjeta con SKU, ASIN y título al inicio de los gráficos
- Incluir Buy Box Warning Badge si el producto tiene issues
- Solo se muestra cuando hay un único ASIN seleccionado

The free-text ASIN search was unclear and not working as expected.
Replace it with a proper MultiSelectDropdown (same as Market/Category
filters) — selecting an ASIN now strictly filters chart data to that
ASIN only.

- Add date? field to BSRRecord (ISO string YYYY-MM-DD)
- processBSRExcel now extracts and stores the Date column as an ISO date
(handles both Excel serial numbers and string dates)
- VendorDataView groups chart data by date (daily) when dates are available,
falling back to weekly buckets — eliminates straight-line charts caused
by only 2 weekly data points

- Change ?? to || for salesAds/units/revenue in weekly aggregation to guard against NaN
- Add || 0 fallback to ads-only records in mergeSalesAndAdsData
- Fix parseCurrency to check isNaN on all EU-format return paths
- Handle ACOS edge case: cost > 0 with adRevenue = 0 now returns 100% instead of 0%
- Add diagnostic console logging to computeDiD for data flow tracing

Allow pasting multiple ASINs separated by spaces in any MultiSelectDropdown
search field and pressing Enter to auto-select all matching options.
Also switch ads CSV/Excel parsing to header-based column mapping for
robustness across different file formats.

Replace undefined input-field CSS class with explicit Tailwind dark theme
classes (bg-slate-800, border-slate-700, text-slate-200) to prevent white
background on form fields.

Replace the basic CRUD experiment tracker with a scientifically rigorous A/B testing system:
- Add DiD analysis engine (services/experimentAnalysis.ts) that computes treatment vs control
group comparisons across 7 metrics (units, sessions, CVR, CTR, ROAS, revenue, ACOS)
- Implement Bayesian verdict system (Winner/Loser/Inconclusive) using posterior probability
with normal CDF approximation (Abramowitz & Stegun erf, no external deps)
- Build counterfactual time series for trend charts (actual vs estimated without change)
- Rewrite ExperimentsView as single component with 3 inline sub-views (list, detail, create)
replacing the previous modal-based ExperimentDetail and ExperimentForm
- Add control group support, change annotations (before→after diffs), and SEO experiment type
- New types: ExperimentChangeAnnotation, DiDMetricResult, DifferenceInDifferencesResult,
ExperimentVerdict
- Simplify App.tsx by removing experiment modal state (5 useState hooks eliminated)
