/*
 * client/styles.css -- pot-strains.com
 *
 * DESIGN BRIEF, since the visual decisions here are arguments and not taste.
 *
 * Every strain site looks the same: green gradients, leaf iconography, a photo
 * of a bud at the top of a thousand words. This one is a DECISION INSTRUMENT.
 * It should read like a spreadsheet that respects you -- dense, monospaced
 * numerals, restrained colour, no stock photography. The brand green appears
 * in the wordmark and nowhere near a data value.
 *
 * COLOUR ENCODES MAGNITUDE ONLY, NEVER CATEGORY.
 *
 * Sought effects and adverse effects are NOT distinguished by red and green.
 * Red/green is the one pairing a colour-blind reader cannot separate, and this
 * is a site where mistaking "6% anxiety" for "6% euphoria" is the whole ball
 * game. Category is carried by column grouping, an explicit heading, and a
 * '+'/'-' sign on every weight. Colour is a single-hue ramp that means "bigger
 * number", and it means that in both groups.
 *
 * Numbers are tabular-figure monospace everywhere, so digits line up in a
 * column and a reader can compare down the page without reading each one.
