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.

NameplateSVG composites the name, the asterisk and the expiry over whatever is already on the card.

1face   "mono" | "serif" | "sans"
2pos    "top" | "middle" | "bottom"
3light  true  = white letters with a black border
4       false = black letters with a white border

Only two ink pairs exist, and that is not a limitation waiting to be lifted. Both read on every background there is; a free colour choice does not, and mid-grey lettering on a mid-grey drawing is exactly what somebody will pick.

`now` is deliberately absent from the signature. Nothing here counts down, so nothing here needs the clock — see the note on the expiry.

RegisterWithLedger hands the ledger this realm's renderer. Anyone may call it: it only ever registers THIS realm's own drawing, and the ledger refuses unless this realm is the one it has approved.

SkinCardSVG draws a skin token's own listing card.

1name   the skin's name, as the shop shows it
2art    the sprite string
3lock   the extension it is restricted to, or "" for one that goes
4       on any name
5light  true  = pale lettering on a dark matte
6       false = dark lettering on a pale matte

The return is a whole document rather than a fragment, because unlike the nameplate this composites over nothing — it IS the card.

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