/* A New Page, THE READING-CHECK SAMPLE POP-UP (/css/anp-checksample.css, Joel's Part 8 "R", Oct 17 evening).
   The same cream picture book as the story samples (css/anp-sample-popup.css): paper cream #FFF8EC, navy text, 24px corners.
   One item at a time with two big buttons, then ONE gentle reveal (a sound map of round chips). It must fit without scrolling
   at 1280x800 and 390x844. Pairs (WCAG AA): navy #1F2E55 on cream/white 11 to 13:1; muted #4B5674 on cream 7:1; white on green
   #1E6B43 6.3:1; navy on gold #F2B544 7.3:1; navy on the Littles pastels (all light) above 9:1.
   Reduced motion: the chips are simply drawn in their final state (no transition at all). */

/* =====================================================================================================================
   Part 10b (Oct 18): the check now ends on a BRIDGE CARD that opens the sample story at the level it found (js/anp-checksample.js).
   Look and feel (Joel's spec): 5 to 10 = map parchment #F3E6C8 with ink #13294B (11.7:1); teen = navy #1F2E55 with #E4E5F0 (10.6:1) and a
   burgundy #5A1A2B case-file tab (white on it 13:1). Heading Fraunces 24px. Known chips are filled in the age accent (5 to 10 teal #0B6E6E
   with white, 6.05:1; teen sea-glass #7FD8C8 with #131C34, 10:1), the next chips are outlined, later chips are soft. One 300ms fill on
   arrival, then still; none under reduced motion. The tiny story page is a white card (teen: navy card) with the sentence in Lexend 26px
   and a 2px teal (teen sea-glass) underline under the known sounds, never a fill. The gold button is navy #1F2E55 on #F2B544 (7.26:1).
   Progress dots: map footprints (5 to 10) and case-file ticks (teen); still.
