/* Range — instrument language.
   Deliberately unlike the other five sites, because six legal pages that share a look are
   the same 4.3(a) signal as six apps that share a look:

     site-intone   dark plum, straight tick-rule masthead, keyline panels with inset legends
     site-rota     dark violet, inline styles
     site-runway   light cool slate, ruled rows, right-aligned money
     site-verdant  warm cream, serif, botanical
     site-tally    warm paper, seven-column week strip, numbered form fields

   This one is a measuring device: cold slate and electric blue, a protractor arc instead of
   a rule, degree figures in monospace, and readings set as bordered blocks. Intone is the
   other dark instrument page, so the two are kept apart on hue (plum vs slate-blue) and on
   the masthead figure (straight ticks vs a swept arc).

   Palette is the app's own `RangeInk` (apps/range/Range/RangeConfig.swift, 0x4FC3F7 accent
   on 0x0B1016) so the page and the app read as one product.

   No rounded cards, no shadows, no gradient buttons — that was the shared vocabulary. */
