/**
 * Direct Mail target-area field styles.
 * Author: Murtaza — 17 September 2026
 *
 * Every rule is scoped under .dm-target-area so the pages' existing
 * stylesheets (campaign_builder.css, direct_mail_build_mailing_list.css,
 * shared_mail_targeting_tool.css, ...) are untouched. Loaded after them, so
 * these overrides win where they overlap.
 *
 * Theme (8 October 2026, from the Figma address bar): teal brand #067577,
 * panel #eef6fc, white inputs with an inset shadow and no border, DM Sans
 * (inherited from base.css) 700 / 18px in #1a629e. Labels and hints stay in
 * the markup for assistive technology but are visually hidden, because the
 * design shows the prompt as placeholder text only.
 *
 * Colours, radii and shadows read the --pl-* tokens from theme.css.
 *
 * Edit log:
 *   30 Oct 2026 - Read --pl-* tokens.
