/*
 * The one stylesheet for every Drop page (brief 063). Plain CSS, no framework,
 * nothing loaded from anywhere else: system fonts only.
 *
 * Utility first. On a phone, above the fold, there is the note, the photo
 * button and Send, and nothing else.
 *
 * The brand's colour arrives as two custom properties, --brand-color and
 * --brand-text, set by a small <style> block the Worker writes on signed-in
 * pages. Every use below carries a neutral fallback, so a brand with no
 * usable colour (and the plain pages, which never know the brand) look
 * finished, not broken.
