/**
 * Map a PDF point to a pixel in the analysis raster.
 *
 * The browser services build the densitometer / color-picker analysis raster
 * at a nominal `ANALYSIS_DPI`, but **downscale it** when a large-format page
 * (a big packaging dieline) would exceed `analysisPixelCap` — so the raster's
 * real resolution is `widthPx/widthPts` px-per-point, which on a capped page is
 * *less* than `ANALYSIS_DPI/72`. Sampling must use that actual ratio, not the
 * nominal DPI: with the nominal scale every point past the capped width maps
 * beyond `widthPx` and clamps to the raster's right/bottom edge — the white
 * margin — so the readout shows `#FFFFFF` · 0% CMYK · 0% TAC no matter where you
 * tap. Deriving the scale from the raster's own dimensions is exact whether or
 * not the cap fired (and is sub-pixel-accurate even when it didn't).
 *
 * PDF points use an origin at the lower-left; raster pixels use the upper-left,
 * hence the Y flip. The result is clamped into `[0, widthPx-1] × [0, heightPx-1]`
 * so an edge tap (or a degenerate zero-dimension raster) never indexes out of
 * bounds.
