/* * Masterica · doc-summarizer — FROZEN engine stylesheet (UEB-154 v1). * * What this file is: * • Design-tokens (colors, type-scale, spacing, radius, shadows). * • Layout primitives (.ms-shell, .ms-header, .ms-main, .ms-footer). * • Component primitives (.ms-card, .ms-input, .ms-button, * .ms-tabs, .ms-tab, .ms-dropzone, .ms-loader, .ms-traffic, * .ms-risk, .ms-alert, .ms-disclaimer). * • Light + dark themes (mode via ``data-theme="dark"`` on ). * * Why it is frozen (DO NOT MODIFY): * Pre-UEB-154 every doc-summarizer build invented its own CSS. Result * (forensic build-90f520d0fb53): forgot to hide spinner on success, * monospace font on result blocks, sticky footer overlapping content, * no traffic-light for risk score. Every regression cost an * acceptance scenario. UEB-154 freezes the visual surface so Builder * ONLY writes content blocks (Jinja `{% block %}`s) and never CSS. * * How Builder customises: * • Title / subtitle / CTA labels → ``templates/index.html`` blocks. * • Theme tokens (primary / accent) → ``static/app-config.json`` * (read by base.js, sets CSS vars on ). * • Result rendering → use ``.ms-card`` / ``.ms-risk`` / * ``.ms-traffic`` classes; DO NOT add ``
`` for plain text.
 *
 * Naming convention: ``ms-`` prefix (Masterica) — never collides with
 * Tailwind / Bootstrap utility classes a Builder might paste in.
