/* ==========================================================================
   Training plans — browse, detail, builder, import
   --------------------------------------------------------------------------
   A plan is a *sequence*, so everything here is built to read top to bottom:
   numbered blocks down the left, and the "for you, today" forecast pinned
   beside them so the student can see what a change costs before they commit
   to it.

   Built-in plans are read-only. That is enforced by `plans.py`, and said out
   loud here — a disabled-looking control that silently does nothing is worse
   than no control, so a built-in never renders an edit affordance at all, it
   renders "Duplicate to edit" instead.

   Tokens only, from base.css. `.notice`, `.dot` and the profile pieces live in
   dashboard.css, which every page in this module also pulls in via base.
