   watts.css — WattCost site-local layer
   AAA+++ STUDIO PREMIUM, §5 row "watts": company voice = SWITCHBOARD SCHEDULE,
   signature set piece = the annual-cost METER BAND.

   Loads AFTER styles.css and data.css, so every value here is an override or an
   addition in the site's own drawing hand. Nothing in _shared/ is touched.

   THE DRAWING HAND (must not be confusable with a sibling's):
   rectilinear only. Square terminals, butt-cap rules, 1px hairlines that meet
   at right angles, digit cells divided like the windows on a kWh meter, a
   DIN-rail tick ruler under the register. Explicitly FORBIDDEN here: round
   caps and arcs (those are RunCost's fuel-gauge hand), dashed contour rings
   (LuxPlan), plate/circle charts (ThaliFacts, DietPlanIndia). An electrician's
   load schedule is drawn with a ruler and a square, and so is this.

   CLS 0.00 is a hard constraint and the odometer is the only thing on the page
   that JavaScript rewrites, so every part of it is dimensioned in advance:
   a fixed six-cell register (leading zeros are printed, not hidden, exactly as
   a real meter prints them), fixed-width mono scale labels reserved in `ch`,
   and a marker that moves by `left` on an absolutely positioned element. No
   text node the script can rewrite is allowed to affect layout.
   ========================================================================== */

   readers get the finished page and nothing animates below the fold.
