/*
 * pm-formula-card.css
 * ===================
 *
 * Triple-view formula card styling for Sprint 3.6.
 *
 * Renders the three SSoT representations of every formula side-by-side:
 *
 *   1. Arithma rendered LaTeX  (from formula.arithma_latex)
 *   2. EML rendered LaTeX      (from formula.eml_latex / eml_tree_compact)
 *   3. Evaluated float         (from formula.value)
 *
 * Plus a fourth action row that hosts:
 *   - [Trace to b3]  - opens dependency graph (Sprint 3.7 owns the graph)
 *   - [Show JSON]    - inspect the raw formula record
 *   - [Show alternatives] - swaps in alternative representations
 *
 * The card border turns yellow when arithma_latex and eml_latex differ after a
 * normalization pass (strip whitespace, lowercase) - this surfaces the
 * Sprint 2 cross-check disagreements (e.g. n_gen = chi_eff / (4 * b3),
 * dark-force leakage, etc).
