Nativer 2D-Viewport: Raumstempel-Text (Einstrich-Vektorschrift)
Neues strokeFont.ts (kompakte Einstrich-Schrift: A-Z, 0-9, Symbole inkl. ²/·). toRenderScene wickelt Text-Primitive (Doc-Zeilen + Live-Zusatzzeilen) zu Glyph- Polylinien in Modell-Metern ab (vertikal um den Anker zentriert, Ausrichtung je Absatz) und speist sie wie die Schraffuren in die render2d-Szene. Erste Fassung in Versalien; render2d bleibt textrenderer-frei. Damit zeigt der native Grundriss den Raumstempel (Name/Fläche/SIA) analog zum Browser.
