/*
 * Colloquy app-page shared theme (/shared/app-theme.css)
 *
 * ONE stylesheet for the plain app-page family (/transmitter, /sensor-demo,
 * and — when its next revision adopts it — /sensor). It extracts the display
 * client's look (display/index.html palette + panel/button idioms, the same
 * scheme the sensor page already uses inline) so every page reads as one
 * product. Page-specific CSS stays minimal on top of this file.
 *
 * The display client itself keeps its own inline styles — do NOT link this
 * file from display/index.html.
 *
 * Served at /shared/app-theme.css (prepare-public copies shared/ into
 * public/; the local dev servers serve the repo root directly).
