/* The four skill colours: the app's colour language (Chris 09-23). ONE place for them.
   Since 10-24 they ARE the four cubes of the SKYONOMY logo (static/css/sky-loader.css, the
   cube BODY colour; Davy saw they did not match, Chris: make them match):
     writing = blue cube, reading = green cube, speaking = red cube, listening = purple cube.
   Read by the assignment wizard (SkillStep / WizardHeader / SpeakingFlow), the teacher's
   assignment list, the pupil profile and lifelong record, and the family pages (which load
   only this file, not sk-tokens.css). Server-rendered output (PDFs, charts, Holly cards)
   reads the mirror in modules/common/skill_colours.py; tests/test_skill_colours_match_logo.py
   keeps the two equal. Never re-type these hexes elsewhere.

   --sk-skill-<x>      the true logo colour: fills, bars, chips, dots, lines.
   --sk-skill-<x>-ink  the same hue cut darker for TEXT and ICON GLYPHS on day surfaces: AA
                       4.5:1 on #fff, on #f4f4f5 paper AND on a 6-14% tint of the skill
                       colour, and white words on an -ink fill hold 4.5:1 too (#2926).
                       Blue and green fail as text (3.2:1), red fails on paper; a chip with
                       white words is filled with the -ink, never the day colour.
   --sk-skill-<x>-dk   text/glyphs on a DARK surface: the logo colour mixed with white,
                       4.5:1 on the night card (#2b2a28) and on a night tint of itself.

   Not themed (the family pages and the always-day header read these too): a page's dark
   rules pick -dk. Presentation (PPT Drop) is drawn in the neutral ink, not a fifth hue. */
