/* Hearth on a phone.
 *
 * The palette, the pixel animations and the header/stamp styling come from
 * design/hearth-kiln.html; where a rule is the mock-up's own it says so. The
 * layout is the phone's: a full-height dark stage per screen, figures in the
 * top part, the 48x48 scene anchored to the bottom, a tab bar for chapters.
 *
 * The one hard layout rule, from PROJECT.md §6: text never sits on the art,
 * and there is no scrim to make it. Each screen's text box stops above the
 * scene's top half (row 24 of 48; the art itself starts at row 27), and
 * tests/test_layout.py checks the bounding boxes at 360 and 430 px.
