/* The route graph page (routes/graph.md), drawn by javascripts/route-graph.js.
 *
 * Three palettes, each run through a validator against both of Material's
 * surfaces (white, and slate at hsl(232 15% 14%) = #1e2129):
 *
 * - Archives, on nodes: five categorical hues in column order -- GEO orange,
 *   NCBI blue, EBI green, DDBJ violet, ArrayExpress amber -- so every pair of
 *   neighbouring columns passes the validator in both modes (worst adjacent
 *   colour-blind dE 24.7 light, 26.8 dark; worst normal-vision dE 27.5). They
 *   do NOT pass on every pair: NCBI blue and DDBJ violet are dE 1.9 apart to a
 *   protan reader, GEO orange and EBI green 3.2. Colour is therefore never the
 *   only channel: each archive is a column, and every label names its archive
 *   ("SRA run", "ENA run", "DRA run"). Amber is 2.17:1 on white, so its nodes
 *   carry their name inside them -- the relief the validator requires.
 *   Records all three INSDC archives hold, and read formats no archive owns,
 *   are neutral.
 * - Resolved share, on measured route lines and matrix cells: a five-step
 *   neutral ink ramp, so it cannot be read as the blue of an INSDC node.
 *   Ordinal checks pass in both modes: lightness monotone, every step gap at
 *   least 0.06, one hue, and the faintest step at 2.25:1 on white and 2.40:1
 *   on slate. In dark mode the ramp runs the other way -- a higher share is
 *   always the higher contrast.
 * - Outcomes, on the bars in panels: resolved is ink, empty is pale, failed is
 *   red (worst colour-blind dE 13.3 light, 20.3 dark). Empty is meant to be
 *   faint -- the archive answered and holds nothing -- and every value it
 *   carries is also in the panel and the table.
 *
 * A surveyed link is not on the ramp either: a hollow solid line -- a stroke
 * with a surface-coloured core -- of one width, in a cool grey (--rg-surveyed,
 * 5.5:1 on white, 6.8:1 on slate) that sits apart from the ramp's warm greys
 * and is far too desaturated to read as NCBI blue. It carries counts and no
 * rank, so it takes neither the ramp's ink nor a route's width.
 *
 * An untested link is not on the ramp at all: it is a thin dotted line with a
 * hollow arrowhead, because it carries no quantity to encode.
