/* Catnnections
   ------------------------------------------------------------------------
   The game's own rules. Tokens, the page frame, the masthead, buttons, list
   rows and empty states come from ../shared/taskcat.css, which index.html
   loads first; this file only adds what the board, ladder and builder need.

   Palette note: the four difficulty hues do double duty — they colour the
   groups AND the rank ladder. That is a rhyme, not a collision: purple means
   "hardest" in both places. Form keeps them apart (tiles are squares, the
   ladder is a bar), so the two readings never compete for the same glyph.

   The player never sees a number. The bar and the rank name are the score.

/* Offscreen ruler for tile text, so app.js can read a word's width in em.
   Measured at 9px, the same value as the font floor below, because a word's
   width in em is not constant across sizes — glyph advances grid-fit to whole
   pixels, making text ~10% relatively wider at 9px than at 100px. Measuring at
   the floor yields the widest em a word can have, so the fit errs small rather
   than wrapping. Weight 800 is the heaviest a tile renders (painted), so a fit
   survives a paint. Keep these declarations in step with .tile below — that is
   what makes the measurement match the tile instead of approximating it. */

/* ---- Caps ---------------------------------------------------------------
   Every string that belongs to the PUZZLE — its title, its group names, its
   words — renders upper case, in the builder and on the board alike. It used
   to be uppercase in some places and as-typed in others, so a puzzle written
   in Title Case shouted in the word grid and then whispered its own words
   back in the solved list (Aaron, 2026-09-19: "both pages should force
   all-caps for all text").

   This is a DISPLAY rule, not a storage one: the stored document keeps what
   the author typed, matching stays case-insensitive through `compareKey` in
   puzzle.js, and every puzzle already saved is fixed by the same stylesheet.
   The one string left alone is the author's own name in the byline — that
   names a person rather than the puzzle, and caps there reads as shouting it.
   Placeholders are exempt everywhere: they are the app talking, not content.
