   Peptide Planner — page styles
   ------------------------------------------------------------
   Uses theme tokens from shared.css. No new CSS variables
   introduced. Components built here:
     - .calc-shell--xwide  (wider variant for the planner)
     - .compound-grid      (compound selector tiles)
     - .vial-row           (vial-size + bac-water + concentration)
     - .schedule-table     (the editable phases table)
     - .summary-strip      (totals readout)
     - .pk-section         (chart wrapper + caption)
     - .pk-note            (caveat panel for non-PK compounds)
     - .info-card--compound (compound-specific notes + sources)
