/* ============================================================================
   hub.css — Latida instructor home (v4). Restrained dark dashboard; the workout
   profile chart is the hero. Effort colors (STANDARD ramp — cyan/green/yellow/orange/red,
   Family A canonical) are DATA-VIZ ONLY (chart, block chips/refs). Status colors are
   CHROME ONLY. Condensed uppercase is limited to nav / card titles / stat labels /
   eyebrows; all numbers + table data render in the normal-width face with tabular-nums.
   Scoped under body.hub-v2. The effort ramp is defined ONCE in dashboard.html's RAMP
   array (queued for deck/TV/builder migration; applied to hub only for now).
