/*
 * Outlook Relook — Swiss / Helvetica Theme
 *
 * Inspired by the International Typographic Style.
 * Helvetica Neue. Black, white, grey, and one accent color.
 * Grid discipline. Content-first. Zero ornament.
 *
 * IMPORTANT: We scope surgical resets to specific OWA containers.
 * Never use `*` selectors — they break SVG icons, checkboxes, etc.
