nsview/v1 package

BuildSVG renders a token. Everything on the card derives from four stored values — owner, registered, expires, and the domain's drawing — so a renewal moves `expires` and the bar, the time remaining and the years held all follow from it. Nothing is baked at mint: the card is generated on every read, which is what lets a domain's artwork be changed after its names have been sold.

MarkerCentred draws text centred on cx, which is what almost every caller here wants and what the SVG text-anchor attribute would have done for them if a font had been available.

MarkerText draws a line of text as stroked paths.

`size` is the CAP HEIGHT in user units, not an em size: it is the height of a capital letter, which is the measurement anybody positioning this by eye is actually thinking in.

`x` is the left edge and `y` is the TOP of the capitals, matching how the rest of this file positions things and unlike SVG's own text baseline, which is a trap when mixing the two.

The jitter is what makes it read as a pen rather than a plotter. It is derived from the character and its position, so it is stable: the same string renders identically on every read, which matters because these cards are regenerated constantly and a letter that wobbled between reads would look like a rendering fault.

MarkerWidth is what MarkerText will occupy, so a caller can centre it. Counts every character including the ones that draw nothing, because a space still advances.

TokenURI returns the full data: URI for a token, generated on every read so the image always reflects current state (never baked at mint).
