/* Optimus Training — one stylesheet.
   Every colour is a token defined once here. Dark is the default because the
   app is used in a gym; light is a real alternative, not an afterthought.
   The lime reads fine on near-black but fails as text on white, so in light
   mode anything that is text or a hairline darkens to olive while filled
   buttons keep the bright lime with dark text on them. Same app either way. */
