/* Daily Micro Tools : "The Ledger, Committed" design system (Theme A, 2026-09-19)
   ---------------------------------------------------------------------------
   POINT OF VIEW: this site is kept by a meticulous person who does your math
   on paper and shows their work. Not a fintech app -- a green ledger book,
   a good pen, and strong opinions about rounding.

   TYPEFACES (each chosen for a job, never defaulted):
   - Zilla Slab (700): display. Chosen for its slab-serif bookkeeping
     character -- the face on ledger covers and old receipts. Used large
     and tight, never polite.
   - Karla: body/UI. Humanist sans with a slightly hand-set feel; keeps long
     explanations readable against the slab display.
   - IBM Plex Mono: every figure on the site. Tabular numerals are a ledger
     non-negotiable -- columns must align or the page is lying.
   - Zilla Slab Highlight (400): margin notes ONLY. The penciled voice of the
     person keeping the book. Never for UI, never for headings.

   PALETTE (four colors, each load-bearing):
   - paper cream #f4f1e6: the page. Warm, never the default #fafafa.
   - ink black #1a1f1a: primary. Headings, header, rules.
   - deep ledger green #1d4a2c: the working color. Buttons, answers, stamps
     of approval. Deepened from the old teal so the green reads as *green*.
   - rubber-stamp red #b3402a: exactly one accent, used sparingly enough that
     each appearance means something (stamps, the double rule under an
     answer, focus). Never decoration.

   MOTIFS (bookkeeping, not decoration):
   - Ruled lines behind everything; paper grain over everything.
   - Double rules where a bookkeeper would put them: under heroes, under
     grand totals (accounting's double-underline), above the footer.
   - Perforation on the featured tool: it tears out of the book.
   - Rubber stamps, slightly rotated: FREE FOREVER means free.
   - Dotted leaders in the wage index, like a table of contents.
   - Hand-drawn underline under the one phrase each page is really about. */
