   enum; login/form errors; RPE bands; alert severities). Derived with the

   as --color-accent-{100..900}, hue swapped only. Verified in-gamut at every
   step (no sRGB clipping). Use like the accent ramp: 700–900 tinted fills,
   500 base, 100–300 text-on-tint. Reach for these only for real severity/
   status meaning — not as a second and third brand color.

/* ══════════════════════════════════════════════════════════════════════════
   Session block builder (session-builder.js + exercise-prescription.js) —
   the exercise/set/circuit editor inside the session drawer. Hundreds of
   bare, unclassed <input>/<select> get generated across many call sites in
   these two ~1600-line files; rather than touch every template string
   individually (high risk of missing one or breaking a template literal),
   fields are styled by scoping to #blocks (the fixed container id both
   files already target) instead of requiring a class on each one. Buttons
   and containers that already have a stable, single generation point
   (block actions, add-exercise, free-text block, card) were given real
   .btn/.card/.input classes directly in the JS — see session-builder.js.
