/* Kodza — Morph Icons
   Icon buttons that change their mind: the strokes of one icon travel, turn and shorten into the
   other. Play folds into pause, the sound waves fade out under a cross, plus turns into close, the
   list closes up into a grid. Nothing is swapped: the same strokes move. Each one is a straight
   line placed by a transform and cut by stroke-dasharray, never an animated d, so Safari plays it.
   The state is the button's own aria-pressed (aria-expanded on a disclosure): the script flips it
   on click, and so can yours. The first icon shows while it is false, the second while it is true.
   Everything is tuned with the --kz-morph-icons-* variables. */

// Next to this file: morph-icons.css and morph-icons.js, the component's CSS and JS from Kodza, as they are.
// Yours to edit: the markup is plain JSX below.
// The script changes this markup once React has rendered it (it adds layers, splits text, moves
// nodes), so React must not patch it afterwards. When a prop changes, the key gives React a fresh
// element: kodza:destroy stops the script on the old one, kodza:init starts it on the new one.
// data-kodza-manual keeps the script from starting it on its own: the effect below does, once
// React has hydrated the markup (on a page that streams in, the script can load first).
// Built from your data (tabs, rows, options)? Put what the markup is made of in the key, as plain
// values (ids, text, numbers): a change starts the script again on fresh markup. What the visitor
// changes (the open tab, the sort, what they type) is the script's: keep it out of the key, follow
// it with onClick or onInput on the root, and change it from your code as a visitor would (click
// the tab; set the field's value, then dispatch a bubbling input event).
