/* ==========================================================
   Responsive shell v1 — one document, desktop → phone.
   Shared by index.html (app) and console.html (operator).

   Implements the seven shell laws from concepts/shells-v35.html:
     1. The rail is universal — no screen invents its own chrome
     2. The brand mark toggles the rail (and carries the idle beat)
     3. One left-stripe — 2px accent marks the active nav item, nothing else
     4. ⌘K is the principal search, top bar, every screen
     5. Mobile folds, never forks — same rail becomes the drawer. NO BOTTOM TABS
     6. Selection is tint, CTA is fill
     7. Works in black and white first

   Composition law from guidelines/GUIDE.mobile-composition.md:
     - rail costs 0px at phone width (off-canvas)
     - <= 2 rows of chrome above content
     - primary action in the bottom third, sticky
   Card law from DEC-025 (briefs/BRIEF.code-presence.md):
     - Code is the head + the one teal moment when present
     - head CLOSES UP when absent; title never promoted (L3)
     - share action becomes the accent on unshared objects (L2)

   All values from brand/relay-tokens-v35.css. Nothing hardcoded.
