/*
 * index.php's "How it works" section — the three numbered step cards and their button.
 *
 * WHY A FILE OF ITS OWN
 *
 * .process-steps, .step, .step-icon and .step-number appear on index.php and nowhere
 * else. #how-it-works is shared - nonprofits.php and volunteers.php have a section with
 * that id too - but theirs is an ordered list that css/styles.css already styles, and
 * nothing here reaches it, because this file is loaded only by index.php through
 * extra_css. That is also why the #how-it-works rules below still win: extra_css is
 * emitted after css/styles.css, exactly as the inline block was.
 *
 * WHAT WAS WRONG WITH IT
 *
 * Four rgba(244, 75, 166, …) - the retired brand pink, and four of the seven that were
 * left on the whole site. A hex replace does not look inside an rgba(), which is how
 * they survived the brand sweep. Two are a wash behind the step icon and are now
 * --primary-tint and --primary-tint-strong, added to css/styles.css for the purpose;
 * two are button shadows and are now --shadow-brand.
 *
 * Three hand-rolled neutral shadows, now the ramp. Two literal `white`. Two breakpoints
 * outside the style guide's set - 992 and 576 - now 1024 and 480. And one !important
 * that was never needed: .step-icon i is (0,1,1) against .fa-3x at (0,1,0), so it wins
 * on specificity alone.

/* The shadow does not change on hover, and that is deliberate. The ramp reserves
   --shadow-brand for gradient buttons, and there is no second brand shadow to step up
   to; the lift and the gradient swap are the feedback. Inventing a fourth shadow to
   keep a hover state busy is what produced 66 distinct shadows for four jobs. */
