/* PerpArena B/W + orange design tokens (proposal, 2026-10-27, revised the same day on the owner's feedback).

   The system is black and white like X: a pure page (#fff / #000), near-black / near-white text, one grey for
   secondary text and hairlines instead of boxes. Colour carries meaning, never decoration. There are exactly two
   colour families:

   - ORANGE is THE accent (owner, 2026-10-27; it is also the helmet logo's colour). It says "you can act here" or
     "this is where you are / what matters now", and nothing else:
       links and inline actions · the keyboard focus ring · the selected nav item / tab underline · the live-data dot ·
       the primary call to action (one per screen) · a few key highlights (the page kicker, the icon of the
       honest-state callout).
     Dark theme: #ff7a1a everywhere (8.1:1 on #000 as text).
     Light theme: #ff7a1a on white is only 2.6:1, so it is split by job —
       --accent-text #b84d00 for anything you read (links, kicker): 5.1:1 on #fff, 4.9:1 on #f7f9f9;
       --accent #c9520a (the helmet's dark facet) for non-text indicators (focus ring, underline, dot, borders):
       4.47:1, above the 3:1 that WCAG 1.4.11 asks of UI parts but a hair under 4.5:1, so it is never used for text.
       (The first guess, #d95a00, is 3.9:1 and would fail as text.)
     The primary button is the bright #ff7a1a in BOTH themes with near-black text #0f1419 (7.1:1); white text on it
     would be 2.6:1. In light mode it carries a 1px #c9520a edge so the button outline is 4.5:1 against the page.
     Hover lightens to the helmet's eye glow #ffb070 (10.3:1 with the dark label).
   Logo colours (helmet, ~/work/archive/trading-lab-ui/2026-10-27-logo-orange/winner): #ff7a1a main = --accent in
     dark and the button fill; #c9520a dark facet = --accent in light; #ffb070 eye glow = button hover.
     Orange is never used for profit, loss, sides, chart lines, categories or warnings.
   - GREEN / RED are reserved strictly for signed money and R values (return, P&L, R of a trade, a 24h change).
     Never for status, long/short, "live", chart lines or categories. Every signed value also carries its + or − sign,
     so colour is never the only cue. Orange is far enough in hue from both that a red loss never reads as a link.
   - Everything else, including warnings (day halt, sampling, maintenance), is monochrome: weight, an icon and words.

   Contrast (WCAG 2.1, measured): text 18.5:1 light / 17.2:1 dark; secondary 6.1:1 on #fff / 5.4:1 on #000 and
   4.6:1 on --raised (v3: dark --text-2 lightened from X's #71767b, which was 3.9:1 on --raised); P&L light #007a52
   5.4:1, #d3141f 5.4:1; dark #00ba7c 8.3:1, #f4212e 5.1:1 (4.3:1 on --raised: no loss figure sits on --raised in dark,
   so dark rows hover with a ring, not a fill). Light --line-strong #83919e is 3.2:1, so outlined controls, the range
   track, the empty-range dashes and the chart start line meet 1.4.11 (v3, after the a11y review).

   Themes: system preference by default, forced with <html data-theme="light|dark">. */
