 * base.css — DEMO LIGHT · Cofoundy design system (LIGHT MODE)
 * ----------------------------------------------------------------------------
 * Light-mode conversion of v2 (dark) for traditional Peruvian board readers
 * who consume PDFs and dashboards under fluorescent meeting-room light.
 *
 * Light palette decisions (locked):
 *  - Page bg:     #F7F8FB (warm cool gray, not pure white — eye strain)
 *  - Card bg:     #FFFFFF
 *  - Primary txt: #0F1620 (almost-black, not #000)
 *  - Brand cyan:  #2C7BA8 (deepened from #46A0D0 for AAA contrast on white)
 *  - Brand cyan accent: #46A0D0 still used for fills, sparklines, badges
 *  - Status red:  #DC2626 on #FEF2F2
 *  - Status amber:#D97706 on #FFFBEB
 *  - Status green:#059669 on #F0FDF4
 *  - Tier A:      #7C3AED on #F5F3FF (violet)
 *  - Tier B:      #2C7BA8 on #F0F9FF (brand)
 *  - Tier C:      #475569 on #F1F5F9 (slate)
