/*
 * The Slip Splitter (SlipSplitter.js) — one slip broken into several, over the
 * SureTOOLS tab.
 *
 * The shell is the Odds Converter's, which is the Lineup Builder's, which is
 * the player page's: a fixed page that fades while its sheet rises, at
 * z-index 70. Restated here for the reason odds-converter.css gives; there are
 * four copies of it now and they want one `.tool-page` between them.
 *
 * The code field, the platform button and the platform sheet are the shared
 * parts in code-input.css, so this tool's field is literally the Merger's.
 * What is here is what splitting adds: the part-count tiles, and the part cards.
 *
 * Separation is tonal, as everywhere in this corner of the app: white cards on
 * the off-white page, the sunken grey inside them, nothing casts a shadow.
