all top-level and detail categories found in the BSR data.

Replace bar charts with area charts featuring:
- Gradient fill effects for modern look
- Smooth monotone curves
- Proper Y-axis orientation (reversed for BSR where lower is better)
- Color-coded by market with transparency

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.

FR/UK/DE sheets have a 'Status' column that appears before 'Reason',
causing the dynamic detector to pick the wrong column.
Use confirmed indices: FR=col S(18), UK=col J(9), DE=col N(13).

Inventory sheets like 'INV ITALY' were being incorrectly matched as
buybox sheets, adding all their ASINs as false BB lost entries.
Now only sheets starting with 'BB' are processed.

Replace fragile header/column-index approach with pattern-based ASIN detection:
- Scan all cells for Amazon ASIN pattern (B[0-9A-Z]{9}) to auto-detect the ASIN column regardless of headers or position
- Detect country from sheet name with flexible matching (no hardcoded sheet name list)
- Detect reason column from header keywords, no hardcoded column indices
- Remove all hardcoded fallback indices (col 13, 18, 9, etc.) that caused empty results

- Force reasonIdx to column N (13) for BB_ES sheet, same as DE/FR/UK, so dynamic header detection can't override to a wrong column
- Fall back to 'BB Lost' when reason cell is empty instead of skipping the ASIN entirely
- Add B095K8948Z to debug logging alongside B0D3874WSD

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

The previous fix only handled the unambiguous case (day > 12). Dates like
"5/1/26" or "12/1/26" (Jan 5 / Jan 12, 2026) were falling through to
JS's new Date() which parsed them as US format MM/DD/YY, assigning them
to May and December instead of January.
Now any 3-part slash date with a 2-digit year in position 3 and a valid
month in position 2 is treated as DD/M/YY (Spanish/EU convention),
fixing weeks 2-3 of January (days 5-18) showing zero sell-out.

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

All vendor files are linked via Dropbox, making manual upload unnecessary.
Removes the Upload Vendor CSV button, handleVendorUpload handler, and processVendorCSV import.

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
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Fix critical regex bug: /\\d+/ was matching literal '\d' instead of
digits, causing all rows to be rejected (week always = 0)
- Add VendorCSV format support: 'Top Level Category (Rank)', 'Date', etc.
- Derive ISO week number from Date column when no Week column exists
- Process all sheets (not just first) to handle multi-tab workbooks
- Log column names on load to aid future debugging

- Rewrite api/fetch-bsr.ts to proxy BSR.xlsx from the Dropbox URL,
matching the same pattern as fetch-buybox.ts and other data sources
- Add /api/fetch-bsr proxy in vite.config.ts for local dev

VendorDataView was refactored to receive BSR data as a prop but App.tsx
was not updated to pass it, causing the component to crash on undefined
and show a blank screen. Also fixes supabase.ts type errors and removes
dead code.

- Change getWeekStartSunday to getISOWeekMonday for timestamp calculation
- Ensures week alignment between data aggregation and ISO week range calculation
- Fixes incorrect treatment_after average calculation
Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
- Add ISO week calculation functions (getISOWeek, getISOWeekMonday, calculateISOWeekRange)
- Expand experiment dates to full ISO weeks (Monday-Sunday) instead of exact date ranges
- Use actual data.length for averaging metrics instead of theoretical durationWeeks
- Baseline now takes same number of complete weeks immediately before experiment
Fixes incorrect units sold average calculation (was 6.5, now correctly shows 4.33 for 13 units over 3 weeks)

The generic regex /sale/i in ads column detection was matching "Advertising Cost
of Sales" (the ACOS % column) before reaching "7 day total sales" (the actual
attributed sales amount). This caused attributedSales30d to receive the ACOS
percentage instead of the real sales value, making experiment ACOS = 0 or 100%.
- Replace /sale/i with specific regexes: /\d+\s*day.*sale/i, /total\s+sale/i, etc.
- Replace /cost/i with regexes that exclude "cost of sales" columns
- Replace /unit/i with specific regexes for unit columns
- Add diagnostic logging for ads Excel column headers and first-row values
- Revert ACOS 100% fallback (root cause now fixed)

- 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.
