/* Investor portal.
 *
 * Ground and structure follow the internal terminal language: neutral warm
 * paper in light, cool near-black in dark, sharp 3px corners, tabular figures,
 * one restrained accent. The accent is the brand teal, validated against both
 * surfaces (light #0097A7, dark #21A5B5: lightness band, chroma and contrast
 * all pass). Semantic pos/neg carry meaning only and always ship with an arrow
 * and a word, never colour alone.
 */

/* Palette taken from the public site (css/theme.css): its default colourway is
   deep teal, its light one warm paper. Two accent roles, not one:

     --accent        chart marks. Needs 3:1 against the surface and must sit in
                     the dark lightness band, so the brand cyan (L 0.885) is
                     too light here and a mid step of the same hue is used.
     --accent-solid  filled buttons and active states. Needs 4.5:1 for the text
                     it carries, which the site's own teal-on-white does not
                     reach, so buttons use a deeper step.
