/* About page (R-A1..R-A5, round 2 R2-A1..A3, R2-G1..G4). Tokens and components come from cfg.css.
   Rhythm: charcoal hero -> light grey mission/vision/values -> charcoal founder -> light closing band.
   Round 4 (Tyler 9/25): round 2 is the base. Changes only: R4-C cream ground is now the neutral light grey
   (.section--light) and no tan values remain; hero plays her FINAL explainer; R4-3 credentials stay under the bio
   but show in full colour on a light plate so they read on the charcoal founder section. */
