/*
 * style.css — MIMH Abstract Review System
 * Version: 1.11.0 (2026-10-30)
 *   1.11.0 — "1.11.0" block at the END: download bars (.export-bar, .export-stack).
 *   1.10.0 — "1.10.0" block at the END: assignment grid + expertise grid (.grid-scroll, .assign-grid,
 *           .grid-cell--on/--no/--warn, sticky first column), tiny number input, legend keys.
 *           ⚠️ The grids are data-nocards tables: the phone rule ".data-table:not(.js-cards) td {display:block}"
 *           is undone for .assign-grid so they stay grids and scroll inside their own box (stated exception).
 *   1.9.0 — "1.9.0" block at the END: Preview-as amber bar, word-limit warning (.is-over), Review & submit
 *           buttons, conference cards + landing page, copy-link row, email preview frame, plain lists;
 *           button rows wrap on phones.
 *   1.8.0 — Playbook 3.7 §19/§20: phone menu (U-01), Email ▾ / Admin ▾ nav groups, phone card layout
 *           for tables (< 640px), sortable headers + phone "Sort by" bar, 16px form inputs (no iOS
 *           zoom), 44px touch targets on touch screens, Sending & limits page (gauge, kpis).
 *           All new rules are in the "1.8.0" block at the END of this file.
 *   1.7.0 — S-16: every former inline style="" now lives here (components + generated u-*
 *           utilities at the end). The CSP no longer allows inline styles. Reports print
 *           rules moved here, scoped to body.page-reports.
 * Clean, professional UI inspired by minimal academic conference portals.
 * Uses CSS custom properties for easy theming.
 * No external dependencies — all self-contained.
