/* ─────────────────────────────────────────────
   edison-hud-canvas.css — the Lab HUD's canvas frame (issue #190, Lab HUD
   2/4; mockup docs/design/editor-hud/1-lab-hud-full.png). Corner brackets
   and the Breadboard title block (built by edison/hud-status.js), the hint
   as a caps grey line at the bottom, Clear All and Reset View as square
   outlined buttons, the scope and meter as thin-framed instruments.
   Every rule is scoped to html[data-ui="edison"], so classic is untouched.
   Caps come from CSS only (the HUD stylesheets' approved exception), so the
   DOM text stays what classic and the tests read. Loaded after
   theme-edison.css, so these win over its viewport rules.
   The text blocks sit on --hc-veil, the HUD black at 88 %: over the dark
   floor they read as the mockup's bare text, and they stay legible when the
   camera puts the white breadboard behind them.
