 * E-ink view (?eink=1): two layouts share this file.
 * - Landscape (default, no ?stop param): 800x600, Kindle mounted physically
 *   rotated 90°, render pipeline rotates the screenshot back into the
 *   panel's native 600x800 framebuffer. 3 boards side by side.
 * - Paged (?eink=1&stop=N): 600x800 portrait, Kindle mounted normally, one
 *   board full-screen, cycled on-device via physical page-turn buttons.
 *   See the html.eink.paged block near the end of this file.
 * Urgency is encoded by weight/shape/inversion, not hue — a 16-level
 * grayscale non-backlit panel dithers close hues into indistinguishable gray.
 * Every rule here is scoped under html.eink so this file is a no-op
 * otherwise, safe to always link from index.html.
