/* Hallmark · v2.0.0 · theme: workbench (custom, by request: похож на opencode) · genre: modern-minimal
   critique: editor-like dark workspace; amber signal, mono accents, square-ish surfaces, no gradients, no emoji.
   waive: 47b — session status is a functional signal, rendered as a small CSS dot with a text label.
   waive: 24b — editor-density spacing deliberately uses 1px increments in code and tool chrome.
   waive: 3 — the accent side stripe marks actionable permission and toast alerts, not decoration.
*/
/* Hallmark · waive 24b · opencode editor-density uses 1px increments for tool chrome · compact code readability at 15px body size */
/* Hallmark · waive 39b · opencode app controls keep 36 to 44px; the flagged 22px is a native radio inside a 32px option row · the label is the hit target */
/* Hallmark · waive 72 · session rows and tabs clip long titles with ellipsis · opencode session rows use 8px padding and verified browser renders */
/* Hallmark · dismissed 3 · permission and toast side stripes carry alert state alongside readable text · checked in desktop and mobile renders */
/* Hallmark · dismissed F24 · command menu floats over the composer and needs elevation · border plus shadow defines the popover edge */
