#6241 deleted the --font-weight-* scale from globals.css and its fontWeight
mapping from tailwind.config.ts. font-medium jumped 440/480 -> 500,
font-semibold 500/550 -> 600, and body dropped 420 -> 400, so every existing
call site snapped a full step above a body that got lighter. #6291 fixed
packages/emcn only; the product call sites were left behind.
Strips the weight class from body, label, row, and heading text across
app/workspace, ee, workflow-renderer, the non-workspace route groups, and
components/ui/button.tsx, whose buttonVariants injected font-medium into every
consumer. Keeps it only where it steps up: markdown/prose bold and micro
avatar initials.
Also aligns the workflow-tree folder chevron to the sidebar section header
(14px, 150ms), and on the feedback modal drops the prompt line above the
Feedback field and re-homes Copy ID as a footer secondary action.
