/* ==========================================================================
   17 · Doc 9 — the PCB viewer, schematic browser and parts tables
   --------------------------------------------------------------------------
   Everything here is scoped to .el-pcb / .el-sch / the generated tables, so it
   cannot reach any other chapter. Consumes the tokens from extra.css §1 and
   adds one family of its own: the layer colours.

   Layer colours are the single deliberate exception to the "no raw colours"
   rule, for the same reason the wiring diagrams are: the colour IS the data.
   Eight copper layers have to be told apart at a glance, and amber and ice are
   reserved for interaction and selection, so they cannot also mean "front
   copper". Each value clears 3:1 against the board fill.
   ========================================================================== */

   Material's ".md-typeset ul:not([hidden])" outranks a plain class selector. */
