/* Leeds Emergency Plumbers — demo stylesheet (Wave 3, V0.4).
   Art direction: a calm typographic noticeboard. A tall poster hero sets the formal
   identity in condensed uppercase type beside one narrow side rail carrying stable
   vertical rules, concentric pressure rings and cropped waterline arcs; a row of
   cropped pressure arcs rises from the hero's lower edge. Below it three compact
   horizontal issue bands index the supported labels against persistent group names,
   then a grounded address-and-contact field and one decisive call close.
   Deliberately no clock, countdown, alarm beacon, speed line or flashing surface.
   Palette: graphite, cool bone paper and one muted pressure teal.
   Hierarchy comes from type scale, rules and whitespace — no cards, no badges. */
