/*
 * SmartPonics platform styling.
 *
 * Colour has two separate jobs here and they never borrow from each other:
 *   - brand colours (the SmartPonics green/cyan) appear on the masthead and nowhere else;
 *   - data colours come from a validated categorical palette, with status colours reserved for
 *     good / warning / serious / critical and always paired with an icon and a word, so nothing
 *     is ever carried by hue alone.
 *
 * Both themes are selected rather than flipped: the dark values are their own steps chosen against
 * the dark surface. Layout uses logical properties throughout (inline-start/end rather than
 * left/right) so the Arabic RTL interface is a direction change, not a second stylesheet.
 */

/*
 * Dark is the default. The platform is read on a phone in a greenhouse and on a screen in a control
 * room, and both are better served by a dark surface — light stays available on the toggle.
 *
 * Two colour groups are deliberately NOT part of the visual refresh: the categorical chart series
 * and the four status colours. Those were chosen against colour-vision-deficiency and contrast
 * thresholds; a neon accent that looks good on a hero would fail both as a data colour. So the
 * accent dresses the chrome — buttons, brand, focus, glow — and never the data.

 * eye finds the column titles without hunting. Alternate rows are tinted very faintly — a wide row
 * of figures is where a reader's eye slips a line, and this is the cheapest fix there is. And the
 * numbers are set in the display face with tabular figures, so digits sit in columns and a decimal
 * point stays put down the whole column.
 *
 * Padding is symmetric and logical rather than "7px 10px 7px 0". That old value put the whole
 * gutter on the physical right, which is the start of the cell in English and the end of it in
 * Arabic — so every table on the platform was padded on the wrong side in one of its two languages.
