/* ---------- the page: panels that fade in, in place, as you scroll ----------

 * "leave your name" sheet fades in over the details. Neither slides: each sits in a "hold",
 * a box taller than the panel by the length of its fade (--f1, --f2). The panel is sticky
 * inside its hold, so it stays put on screen for exactly that much scrolling, then scrolls on
 * as normal. JS only sets how far each fade has got (--in, --cover), never a position.
 *   intro-on (boot.js): the details card's hold starts under the pinned opening.
 *   flow-on (app.js, needs --card-h and --sheet-h): the card pins once it has been read
 *   and the sheet gets its own hold. */
