 - Button icons must be placed before the label in DOM order, with the icon and label centered together as one group. Keep the control's chevron or disclosure arrow in its own fixed right-side slot so it does not shift the centered label.
 - Use one shared icon size, gap, alignment, hover state and disabled state for equivalent controls. Do not mix icon-only, text-only and icon-after-text variants for the same control family.
 - Before finishing any UI change, inspect the rendered page with Playwright and verify that icons are visible, precede their labels, remain centered, and do not overlap or drift between controls. Update this file when a new reusable visual rule is discovered.
+- Custom select controls may use a native select as an interaction layer, but the native label must be visually transparent when a separate display label is rendered; never show the same control text twice.
+- Runtime button labels must update the existing direct child label span instead of replacing `button.textContent`; state changes must never remove the button icon.
+- Parser tools are always visible in the left panel. Do not hide, collapse or replace the parser action buttons with a toggle; the user must see the complete parser action set at all times.
+- Mapping status and mapping source details belong beside the database connection status at the bottom of the sidebar. Style it as a shared sidebar section header with icon, centered status and a fixed right chevron; keep the existing mapping behavior.

 - Use Playwright for all supplier/manufacturer website scraping and browser page inspection.
 - Do not implement new scraping with raw `fetch`, regex-only HTML parsing, Selenium or direct HTTP shortcuts.
 - Scrapers must use controlled browser navigation, selectors, explicit waits and bounded request counts.
+- The configured browser engine for a source is authoritative. If a source says `firefox`, launch Firefox or fail loudly; do not silently fall back to Chromium, Edge or another browser.
+- Visible source windows, URL health checks, source lookup and picture parsing must all use the same configured browser engine from that source's database setting.
+- Source candidate `Open` actions in the UI must call the backend source opener with `manufacturerId`, `sourceKey` and URL. Do not use plain `target="_blank"` source links for mapped supplier/manufacturer sources because that ignores the configured browser engine.
 - Keep scraping slow and observable, preserve source URL/status information, and handle blocked pages or missing selectors as explicit errors.
 - Supplier data remains a local draft until the user explicitly confirms an Apply / Save action.

 - Backend data API routes reject a Live DB request when the project is configured only for MariaDB.

 - `Find sources` searches once and caches candidates for the current product; a second click reopens cached results.
+- The source-candidates popup must provide a `Reload` action beside `Close`; `Reload` bypasses only the current product's cached source result and re-runs the source lookup using the current local mapping configuration. It must not switch database modes or write to Live DB.
 - Source candidates show how they were found, including EAN/reference/name and color context.
 - Each source row has its own `Get pictures` action.
