/*
	Design tokens for the dark editorial direction (G1).

	Ported from mockups/01-dark-editorial/css/styles.css, which is frozen. That file
	scoped everything to a .dark-editorial class because five directions shared one
	document tree; here the direction IS the site, so the tokens sit on :root and the
	scoping class is gone.

	Loaded before home.css and after global.css, so the last four declarations below
	re-point the four shell names global.css invented for the placeholder page. One
	palette drives the page; global.css keeps owning the reset, the fonts and the
	skip link.

	Contrast, computed against the composited background (WCAG 2.1). Every value here
	is a measurement, not an intention: text pairs clear 4.5:1 and rings clear 3:1.

	  #ececf0 text on #0a0a0c canvas ........ 16.79:1
	  #9a9aa4 muted on #0a0a0c canvas ........ 7.09:1
	  #9a9aa4 muted on #0d0d11 lead .......... 6.96:1
	  #9a9aa4 muted on #131317 panel ......... 6.65:1
	  #9a9aa4 muted on a tracker plate ....... 4.67:1  (worst band, worst pixel; see below)
	  #85858f muted-2 on #0a0a0c canvas ...... 5.42:1
	  #85858f muted-2 on #131317 panel ....... 5.08:1
	  #ff5c1a accent on #0a0a0c canvas ....... 6.40:1  (surfaces and rules only)
	  #ff7a42 accent-text on #0a0a0c canvas .. 7.64:1  (the only orange used AS text)
	  #ff7a42 accent-text on #131317 panel ... 7.16:1
	  #0a0a0c ink on #ff5c1a newsletter band .. 6.80:1
	  #3a1206 soft ink on #ff5c1a band ....... 5.36:1

	--muted-2 is the one token with a ceiling: it never goes on a tracker plate,
	where the glow lifts the ground and drops it under 4.5:1. Quiet text there
	uses --muted.

	THE FOUR TRACKER ACCENTS. One exception to the single-orange discipline, and it
	stops at the four full-bleed tracker bands: each band inks its own kicker, dashes,
	row dates, rules and stage markers, and everything else on the page stays orange.
	The release calendar keeps the house pair, so the exception adds three hues rather
	than four.

	  release-calendar ... #ff5c1a surface / #ff7a42 text   (the house pair)
	  tour-guide ......... #f0c04e
	  festival-tracker ... #7ef0c1
	  award-watch ........ #c99df0

	The three new hues are far brighter than the orange, so each one is text-safe at
	full strength and needs no second variant: the --accent/--accent-text split exists
	because #ff5c1a alone fails as ink, and #f0c04e, #7ef0c1 and #c99df0 do not. The
	*-text names below are still declared per band, so a hue that later fails as ink
	gets its brighter variant in one place and every accent-inked rule follows.

	What the brightness costs is the plate. A band's glow and dot screen are inked from
	its own accent, and mint at the orange's opacity would lift the ground far past
	where the orange lifts it, dropping --muted under 4.5:1 across the band. So each
	band carries --plate-ink in home.css, one scale over the whole plate layer, set so
	the band's lit ground composites to the luminance the orange plate already reaches:
	1, 0.64, 0.57, 0.74 for the four above. That holds every accent opacity under the
	orange plate's, which is the ceiling the design sets, and it is what lets the
	neutral figures at the top of this file stand on all four bands instead of only on
	the one they were measured on.

	Contrast below is measured, not modelled: every pairing was read off the rendered
	page in Chrome at 1440, taking the brightest pixel behind the element as its
	ground, which is the glow at its hottest with a dot of the screen on top of it.

	  --muted, quietest text on a plate  4.91:1   4.67:1   4.74:1   5.08:1
	  --text, the band heading ........ 11.93:1  13.06:1  12.57:1  13.14:1
	  key square on the #0a0a0c rail ..  6.40:1  11.64:1  14.24:1   9.01:1

	Every ink clears 4.5:1 and every rule, marker and ring clears 3:1. The tightest
	figures on the page are the two orange ones, at 4.21:1 and 4.46:1, and both are
	rules rather than type; the tightest ink anywhere is --muted under the tour guide's
	lockup at 4.67:1, which is the figure the table at the top of this file quotes. The
	5.48:1 it used to quote was read when award watch was the only plate and that plate
	was orange; the same pairing on the same lockup reads 5.08:1 now.

	The rail's own links are not part of the exception. They are --muted on the canvas
	at 5.40:1 measured over the hairline, and only the key square beside each label
	carries the band's colour.
