/* ==========================================================================
   Hand Lettering for Beginners — main stylesheet
   Design system: tokens, typography, components, layouts, utilities.
   No external dependencies. No remote fonts. No image files. Mobile-first.

   Look: a letterer's desk — warm off-white paper, navy ink, light blue pencil
   guide lines and a coral accent. The signature motif is the pair of lettering
   guide lines (a dashed x-height line above a solid baseline), drawn with CSS
   gradients and borders only.

   Contrast reference (WCAG AA, computed):
     ink          #22303f on paper #fbf8f1 / white ........ 12.7:1 / 13.4:1
     ink-soft     #3f4d5c on paper / desk #eadfce ......... 8.2:1 / 6.6:1
     ink-muted    #55616d on paper / desk #eadfce ......... 6.0:1 / 4.8:1
     accent       #b84a33 on paper / white ................ 4.9:1 / 5.2:1
     accent       #b84a33 on guide-tint / coral-tint ...... 4.6:1 / 4.6:1
     accent-hover #8f3524 on paper / beige / desk ......... 7.3:1 / 6.6:1 / 5.9:1
     guide-ink    #2f5d7a on white / guide-tint ........... 7.1:1 / 6.3:1
     white        #ffffff on accent #b84a33 ............... 5.2:1
     paper        #fbf8f1 on ink #22303f .................. 12.7:1
   The accent is 4.4:1 on beige #f3ece0 and 3.9:1 on desk #eadfce, so links on
   those two backgrounds use ink or accent-hover instead.
   Guide blue #8fb1c7, coral #d9694f and gold #d9a441 are decoration only and
   never carry text.
