 2. Display the fixed set of Latvian-named water-temperature fields.
 3. Enter or correct every water temperature manually.
 4. Place values automatically at their locked production positions.
 5. Preview and download either a 1920×1080 or 3840×1440 PNG.
 
-The background, title, source, field set, and value positions remain fixed. Only the water-temperature values are routinely edited. Both output sizes are production requirements and must be validated independently; implementation must not assume that browser preview dimensions define export geometry.
+The 1920×1080 and 3840×1440 products are independent authoritative canvases. Neither is derived by resizing or reflowing the other. Each template contains the fixed newsroom artwork and six separately measured value rectangles.
 
-When switching output size, the background may use the target canvas aspect ratio, but boxes, typography, and nameplate elements must scale uniformly. They must never be independently stretched on the horizontal and vertical axes.
+The renderer uses canvas `TextMetrics` visible-glyph bounds (`actualBoundingBoxLeft`, `actualBoundingBoxRight`, `actualBoundingBoxAscent`, and `actualBoundingBoxDescent`) to optically center Monda text inside each rectangle. The browser preview scales the complete canvas only; downloaded PNGs retain their native dimensions.
 
-Implementation status: first working version implemented. The page provides six Latvian-named manual min/max controls, automatic fixed placement, Monda rendering, explicit resolution selection, completeness validation, and Latvian PNG filenames. Pixel-level comparison and independent calibration of both output sizes remain required.
+Implementation status: both native exports are implemented and visually validated against the supplied production templates. Later newsroom feedback can still tune the per-template rectangles without changing the manual-entry workflow.
