/* Explore, redesigned (DESIGN-SYSTEM.md §12): the top-level pager of four full-bleed covers (For you, Art,
   Ideas, World), and the Art feed (the old Paintings + Poems lenses merged). New file, so app.css stays
   untouched (js/explore.js, js/gallery.js, js/poems.js). Same "museum editorial" tokens as app.css:
   var(--serif)/var(--mono), the warm-black ground, hairline rules instead of boxes. */

/* ---------- the pager: a vertical scroll-snap of full-screen covers, one great image each ----------
   Redesigned 2026-10-08 (David: "this menu is ugly and odd" on a 16 Pro Max). Each cover is the whole screen,
   edge to edge: the image runs under the status bar and takes whatever the text doesn't (about 60% on a 16 Pro
   Max, 55% on a 375 x 812); then the palette band (its real colors, each a button to its color page), the name,
   one line, today's note, and the paper primary, which sits just above the Rooms corner. No next-cover peek:
   the page dots on the right say there's more. Search is the one solid button top-right, inside the safe area. */
