/*
  Spreadsheets lane — page-specific demo styles.
  Loaded after /main_style.css and /portfolio/portfolio.css.

  Contains: shared demo-chrome helpers (.ds-mini / .ds-seg / .ds-tooltip),
  .ds-* (data-prep tool), .pv-* (pivot builder),
  .inv-* (invoice tool — the intentionally LIGHT paper surface).

  The demos toggle a lot of panels with the `hidden` attribute, and several of
  those panels also carry a display value, so `hidden` is made authoritative
  inside every demo stage.

/* ---- Micro-badge rhythm (dark demo chrome) ----
   .ds-badge and .ds-rule-act are the same tier — small uppercase status
   capsules on the dark demo surface — but carried different padding
   (0.1rem 0.45rem vs 0.1rem 0.4rem) and no line-height, so they rendered
   19.00px and 18.01px tall with mismatched left/right insets. One scale,
   matched to the automation and AI lanes so all four read as one system.

   NOTE: .inv-tag is deliberately NOT in this set. It lives on the LIGHT
   invoice paper — its own visual world, its own smaller type scale — and it is
   constrained by the line box of the table row it sits in. See the note on
   .inv-tag itself for the measurements; it is correct as-is. */
