-Confirmed Monda Regular/Bold files are now bundled and used. The export dimensions are locked, but final pixel-level placement must still be compared against the production masters after the font change. As of 2026-08-23 the 12 other fixed positions load real station data; Valmiera has no matching real open-data station yet, so it currently still shows the last synthetic row generated before synthetic data generation was stopped (increasingly stale, since nothing refreshes it). Once the old synthetic rows are wiped from `weather` (a still-pending step — see `docs/UPDATE_ROADMAP.md` Phase 7), Valmiera will show no data until a real source is found.
+Confirmed Monda Regular/Bold files are now bundled and used. The export dimensions are locked, but final pixel-level placement must still be compared against the production masters after the font change. All 13 fixed positions now load real station data. Valmiera itself has no matching LVĢMC open-data station (confirmed live 2026-08-23); as of 2026-08-25 that position queries Priekuļi's reading instead, chosen as the closest currently-reporting station by measuring against the app's own calibrated map coordinates (~56px away vs. the next-closest candidate's ~81px). Valmiera's marker position and on-map label are unaffected — only the underlying data source for that slot changed. This is a provisional stand-in pending direct confirmation from LVĢMC.

 - Whether weather conditions can eventually be populated automatically and which provider field is authoritative.
-- Whether Stende and Zīlāni remain the production feeds after users test real provider data.
-- Confirm how Valmiera is named and sourced when authorized provider data is available.
+- Whether Stende, Zīlāni, and now Priekuļi (for Valmiera) remain the production feeds after users test real provider data — Priekuļi is a provisional pick pending direct confirmation from LVĢMC.

 - Required authentication and role separation for analytical, production, and administrative workspaces.
