/* ChatFlow flow editor: the Edit Block panel (#panel, design A). Needs tokens.css,
   components.css (fields, check rows, segmented control, menu, chips, icon buttons) and
   flows-list.css (the switch, .flw-switch, and its word, .flw-live-word) first.

   The panel slides in from the right over the canvas: a header (title, the block's Start /
   Post-REG / Post-FTD marks, More, Close), then the block's fields, which scroll. Each action
   is a card with the soft card shadow: a 36px head (drag grip, the action's name, More) with
   no divider, then its fields. Short fields sit on one line with their label ("Duration [4]
   seconds", .fbp-inline); the others have their label above. Sub-cards hold the conditions of
   a Condition or AI Chatter block, one line each.

   Density (colour language rule 1, 2026-09-30): the panel keeps the old one's density, so
   every block that fit a 1440x900 screen before fits again, Reply and Connections included.
   Inputs are 32px here (44px on touch), gaps 8px inside a section and 16px between them.

   Colours come from tokens only, so night needs no rules here; the class names (fbp-*) keep
   the old night layer's .panel, .action-card, .tag-* and .toggle-* rules (deleted with this
   file) from ever reaching it again.

   The canvas and its toolbar are not styled here (the next phase). */
