/* MyEcho type system — the one place font families, the size scale, weights and line heights are defined.
   Every page links this file (before its own <style>) and sets sizes with these tokens, never raw px.

   Scale (16px root): 100 = 11px · 200 = 12px · 300 = 13px · 400 = 14px · 500 = 16px · 600 = 18px
                      700 = 22px · 800 = 28px · 900 = fluid 32→52px (section titles) · 1000 = fluid 40→70px (hero)
   Rules: body copy is never below --fs-400 (app) / --fs-500 (marketing); --fs-100 is only for short uppercase
   labels; form controls use --fs-500 on small screens so iOS doesn't zoom on focus. */
