/* operational-visual-grammar.css
 *
 * Sprint V1-UX-2F — Operational Visual Grammar presentation layer.
 *
 * A NEW stylesheet (linked from index.html alongside styles.css and
 * shared-investigation-state.css) so the 99KB styles.css is left untouched.
 * Everything here reuses the existing design tokens (--red/--orange/
 * --yellow/--gray for operational state, --panel-*/--card-*/--text-* for
 * chrome), with literal fallbacks so it degrades gracefully if a token is
 * absent. No new color/type/radius language is introduced.
 *
 * Two concerns:
 *   1. .ovg-marker — the inline object-type shape marker used on every DOM
 *      surface (Passport, Risk Board, Functional Radar, Timeline, Hover
 *      Preview, Text View). Shape fill is currentColor; the state class sets
 *      the color, so shape (type) and color (state) are independent — color
 *      is never the only signal.
 *   2. The "Operational Visual Grammar" legend (toolbar toggle + flyout).

/* --- Marker/badge + existing-tag grouping ---------------------------------
 * Sprint V1-UX-2F follow-up: several existing rows (e.g. Passport's
 * `.passport-entry-head`) use `justify-content: space-between` across
 * exactly two children. Inserting a new marker/badge as a bare third child
 * would break that two-group distribution. This class groups a new
 * marker/badge with its adjacent EXISTING tag/status/citation span into one
 * flex item, so space-between still sees only two groups and no existing
 * layout rule needs to change - purely additive, no redesign. */
