C3D-0135 · Road name + R/W labels (Sweetbriar Ln, Camellia Cir) [ROAD-LABELS] done

Labels both abutting roads on ROAD_TEXT at height 6.0: SWEETBRIAR LN 50' R/W as a single rotated MText, and CAMELLIA CIR 50' R/W as curved text - one MText per character placed along the centreline and rotated to the local tangent. Road names from Regrid, confirmed against centreline bearings; R/W widths derived from the nearest iron pins (24.44/24.87 and 24.93/26.29 half-widths) doubled and snapped to the standard 50 ft.

C# payload

// Road name + right-of-way labels on ROAD_TEXT.
//
// Roads identified from Regrid (app.regrid.com, parcel 13016C E001) and confirmed against the
// drawn centreline geometry: CL_A is straight S21W = SWEETBRIAR LN, CL_B curves S59E->S29E
// (a constant curve = a circle road) = CAMELLIA CIR.
//
// R/W width comes from the nearest iron pin to each centreline, doubled and snapped to a standard
// width (30/40/50/60/70/80/100):
//   SWEETBRIAR LN  pins 102 (24.44) and 103 (24.87) -> mean half 24.65 -> 49.3 -> 50' R/W
//   CAMELLIA CIR   pins 100 (24.93) and 103 (26.29) -> mean half 25.61 -> 51.2 -> 50' R/W
// If no pin falls within 40 ft of a centreline the label must read "R/W VARIES" instead.
//
// The curved road gets its text CURVED: one MText per character, positioned along the centreline
// and rotated to the local tangent. The straight road gets a single rotated MText.
// Characters that would read upside-down are flipped 180 degrees.
