   Butte Fence Sales Portal — stylesheet

   Mobile-first (design doc S11): reps use this on phones in the field. Layout
   starts single-column and widens at 700px / 1024px.

   COLOR NOTES
   -----------
   Brand navy/rust below is PROVISIONAL — design doc Q5 has "confirm exact
   assets with Tom before finalizing theme". Every brand value is a custom
   property in :root, so swapping in the real palette is a one-block edit.

   The aging ramp is the validated single-hue blue ordinal ramp (steps 250-650).
   A green->red aging ramp was tried first and rejected: its yellow and orange
   steps measured ΔE 10.1 apart for normal vision, below the 15 floor, so the
   1-30 and 31-60 buckets would have been genuinely hard to tell apart. "How
   overdue" is carried by the always-visible bucket label plus a reserved
   status color on past-due figures, never by hue alone.

   Light mode only, deliberately: an internal business tool rendered on one
   known surface. Every color is stated explicitly rather than inherited.
