/* YouMail design system.
 *
 * Concept: the inside of a security envelope. The fine lattice printed on confidential envelopes so
 * nothing can be read through the paper is the one recurring motif; everything else stays quiet.
 * Ink and paper carry the interface, a single highlighter in the logo's gold marks what needs attention
 * (unread mail, where you are, keyboard focus) and stamp red is reserved for destructive actions.
 * Archivo's width axis is the typographic device: expanded for titles, normal for reading,
 * condensed for dates and counts.
 *
 * CSP: style-src 'self', so no inline styles anywhere; images are self-hosted SVG files.
