/* ==========================================================
   EON — Design Flow STRUCTURAL layer (2026-07-06)

   The full editorial system from the operator's DESIGN FLOW boards,
   applied on top of the token skin that shipped in #911: text-only
   nav, cards become hairlines, lowercase wordmarks with a vermilion
   period, giant tabular numerals, [ BRACKET ] micro-labels, accent
   discipline (vermilion speaks once per screen).

   HARD INVARIANT — Classic must render byte-identical with this file
   loaded: EVERY rule in this file is scoped under [data-theme="flow"].
   A source test (tests/test_theme_flow.py) parses the file and fails
   on any unscoped selector; a playwright check pixel-compares Classic
   with and without this stylesheet. Do not add :root, html, body or
   bare-class rules here.

/* ── 25 · Round 3 (2026-07-08): flat cream home + green ink CTA ───
   Operator: "on homepage the page should be cream not grey" — the
   drifting blue/violet ambient washes greyed the bone; flow is flat
   (same law as /marketing), the paper IS the atmosphere. And: "for
   dark mode active button should be green not white" — ink primaries
   go EON-green (accent-solid), not ink-solid. */

/* less motion (2026-09-02): this file is structurally flat — no at-rules,
   every selector scope-parseable (test_theme_flow.py gates both) — so its
   calm twin lives in app.css, on html-prefixed flow selectors that outweigh
   the 0.2s view entry above. Nothing here may wrap a rule in a media query. */
