Kaufland Repricer — Per-SKU Price Push: Add a new API endpoint and UI action to send min/max prices for a single SKU to Kaufland from the articles table (per-row button). This enables targeted price updates without sending prices for the entire catalog.
Otto — Sync New Articles: Add POST /otto/articles/sync_from_otto and a "Sync from Otto" UI action to import product variations that are not yet tracked. The import skips existing SKUs and only adds variations with quantity > 0.

Plenty — Eval file & historical stock values: Allow recalculating stock values for a specific historical snapshot_date (not only the latest snapshot). When recalculating past snapshots the service now regenerates the Plenty eval XLSX so the exported evaluation includes corrected stock values for that date.
Plenty UI: Add a date picker to the "Calculate Stock Values" action so users can select a historical date to recalculate.
Kaufland Repricer — Margin rule logic & min/max prices: Rework margin-rule matching and price calculations:
Rule selection now picks the most specific buy_price threshold (highest threshold ≤ buy price), avoiding accidental matches to broad default rules.
minimum_price is computed to satisfy both the configured minimum margin (%) and the absolute minimum profit (€) (floor = max of both constraints).
maximum_price is computed from the configured maximum margin settings and absolute profit target (ceiling = max of both constraints) and is stored on the article.
maximum_price is rounded to end with .90 (e.g. 55.93 → 55.90, 55.02 → 55.90) to match pricing conventions.
expected_profit is calculated solely from the current kaufland price and is independent from the min/max repricer bounds.

service-invoice: Fix Rituals invoice download special case — follow the click-tracking redirect inside a headless browser using a residential proxy (Playwright + Webshare-style proxies) and download the PDF via proxy when Playwright indicates a direct-download response; fall back to the email attachment if all URL-based attempts fail.
Kaufland Repricer — Rule matching bug: Fix an incorrect fallback and indentation issue that could cause the wrong margin rule to be selected for some buy prices, which previously led to mismatched min/max prices and incorrect profit expectations.
PrepBusiness Simulator — Paste Full Row: The simulator now accepts pasting a complete spreadsheet row (tab/CSV row) to quickly populate a test product entry for simulations and testing.
